Attachment Point Analysis


Solid Brass Swivel Snap Round Eye

round_brass

This is our most popular attachment point for our K9 leads. Made of solid cast brass they are both durable and malleable. They are Marine Grade which means they have been designed to stand up to the most brutal exposure to the elements and continue to function. They have a stainless steel internal spring and a drain hole in the spring cylinder to shed water. They also have a swivel attachment that lets them spin freely which prevents tangles.

Being made of malleable brass they will bend before they break, unlike other snaps cast from different material that are prone to catastrophic failure without warning. This is important because it gives the handler the opportunity to take them out of service before they fail. These attach to the leads with a large rounded eye that was originally designed to be used with ropes. This round eye gives the clip an extra degree of articulation, helping it move more freely and preventing accidental unclipping—which can happen when the snap gets caught on other hardware and the pressure applied defeats the clip.

Pros

  • Made of malleable cast brass that bends before it breaks
  • Spring is made of stainless steel
  • Easy to operate with one hand
  • Round eye gives an extra degree of articulation
  • Swivels freely preventing tangles

Cons

  • Because it is malleable it may not hold as much weight as some of the heavier clip-in options
  • Thumb snap can come open if it gets caught on environmental hazards
  • Can’t take much pressure when cross-loaded
  • Can’t be released under load

Solid Brass Swivel Snap Square Eye

square_brass

This is our second most popular attachment point for our K9 leads. Made of solid cast brass they are both durable and malleable. They are Marine Grade which means they have to be able to stand up to the most brutal exposure to the elements and continue to function. They have a stainless steel internal spring and a drain hole in the spring cylinder to shed water. They also have a swivel attachment that lets them spin freely which prevents tangles.

Being made of malleable brass they will bend before they break unlike other snaps cast from different material that are prone to catastrophic failure without warning. This is important because it gives the handler the opportunity to take them out of service before they fail. These attach to the leads with a 1” square eye that has been designed to be used with flat webbing. This square eye creates a more stable clip-in point than the round eye, making it easier to manipulate with one hand. Because it does not have the extra degree of articulation on the end of the lead, like the round eye, it is more prone to accidental unclippings.

Pros

  • Made of malleable cast brass that bends before it breaks
  • Spring is made of stainless steel
  • Easy to operate with one hand
  • Square Eye gives greater one hand control of the clip
  • Swivels freely preventing tangles

Cons

  • Because it is malleable it may not hold as much weight as some of the heavier clip-in options
  • Thumb snap can come open if it gets caught on environmental hazards
  • Can’t take much pressure when cross-loaded
  • Can’t be released under load

HK Snap

hk_hook

Our solid stamped steel HK Snaps are extremely durable and strong. Originally designed by Heckler & Koch for their submachine guns, these compact but versatile clips can even be clipped into each other through an integrated stamped hole in the body of the clip. They function just like a non-locking carabiner and are easy to manipulate with one hand. If you’re clipping into a solid point all you have to do is press the gate of the clip against the point, the gate will open and can be clipped with one hand. To unclip just use your thumb to press the gate open, pull up to release tension, and remove the snap. This is our recommended clip for our rifle slings.

Pros

  • Easy to manipulate with one hand
  • Extremely strong and durable
  • Less prone to accidental unclipping

Cons

  • Can become unclipped under extreme circumstances where the gate is cross-loaded
  • Can’t be released under load
  • Does not swivel and can create tangles

M.A.S.H. Hook

mash_hook

Made by ITW Nexus, the M.A.S.H hook is the only clip-in option that has no moving parts. Made of stamped stainless steel it was originally designed as a rifle clip-in option alternative to the HK Snap. Because it has no moving parts it can last forever and because it’s made of stainless steel it is very strong. To attach and detach you just press the tabs with your thumb and forefinger, turn sideways, then rotate back and release. It’s complicated to manipulate at first, but once you’re used to it your muscle memory takes over. This is our second most recommended clip-in option for our rifle slings.

Pros

  • Can be attached or detached with one hand
  • Extremely strong and durable
  • Cannot be accidentally unclipped
  • Has no moving parts that can fail

Cons

  • Can’t be released under load
  • Can be difficult to manipulate
  • Does not swivel and can create tangles

Rifle Sling Swivel

rifle_swivel2

One of the earliest detachable sling swivels created, it gives the user the ability to quickly attach and detach their sling from their traditional sling swivel mounts. These mounts are most commonly used on hunting rifles and shotguns. To detach simply depress the spring loaded gate pin and rotate 45 degrees out of the way. To attach just reverse those steps. These have a much more limited application than our other attachment points but are very common on traditional long gun stocks.

Pros

  • Designed specifically for traditional rifle sling attachment points
  • Easy to attach and detach with one hand

Cons

  • Does not pivot
  • Limited application

Quick Detach (QD) Sling Swivel

qr_swivel

Designed for modern rifle and shotgun stocks with QD socket integration, these are very secure and give a large range of motion by pivoting freely once they have been attached to their socket. To remove just depress the spring loaded button on its center with your thumb and pull the swivel out. Reverse those steps to attach it to a socket. These have very few moving parts and are one of the only rifle attachment points that swivel.

Pros

  • Easy to attach and detach with one hand
  • Swivels freely preventing tangles

Cons

  • Requires special sockets in the rifles or shotguns receiver to attach
  • If sockets get clogged with dirt, mud or debris attaching them becomes difficult or impossible

Quick Detach Snap Shackle

qr_shackle_tdl

Our stainless steel snap shackles are some of the strongest and most durable in the industry. Originally designed for marine application as a clip-in option that could be released under load, the clips we use were made specifically for the Special Forces community as part of their aerial platform personal retention lanyards. Being one of the only clips to be both strength rated for life safety application and releasable under tension, it was selected in the event an operator became trapped by their retention lanyard and allowed them to quickly detach by pulling a safety tab affixed to a ring. It’s no longer the preferred attachment option for aerial platforms because of how easy it is to unclip when a full life load is applied, but works perfectly for K9 application where the loads are far less than an operator in full kit. We also have smaller versions of the same clip that can be used on our rifle slings. This is the only clip-in option that we use with our Operator Series Tactical Deployment Lead.

Pros

  • Extremely strong and durable—rated for life safety application
  • Easy to detach under load

Cons

  • Difficult to attach if using just one hand
  • Cannot swivel and can create tangles
  • Easy to detach under load

Kong Frog

frog_cable

This unique attachment option was designed through a collaboration between Kong and the Polytechnic University of Milan as a replacement for the modern day carabiner when used in sport climbing. It was designed to attach to the end of quickdraws and give a quick and easy attachment point to climbing bolt hangers.  They are easy to use and provide a redundant level of safety. When the gates are preloaded open all you have to do is push it onto whatever clip-in point you want and the dual gates automatically close. To unlock it all you have to do is secure the body in your hand and use your thumb and forefinger to pull the tabs back.

Its real strength is its redundancy, making it one of the most secure clip in option available. The downside is that it’s larger and has more moving parts than the other options. Also, it has a tendency to catch on environmental hazards and does not swivel which can cause tangles.

Pros

  • Extremely strong and durable—rated for life safety application
  • Easy to attach and detach with one hand

Cons

  • Larger than most clips and prone to catching on environmental hazards
  • Cannot swivel and can create tangles
  • Cannot be detached under load

Herm Sprenger Scissor Snap

scissor snap

One of the only attachment points specifically designed for K9 use, these heavy duty snaps are the only attachment option that clamp down tighter the harder they are tensioned. To release you just have to use your thumb and forefinger to press the sides together. You attach it in the same way. They are larger than many of the other clip-in options but remain one of the only to be designed specifically for K9 use, making them an important option to provide. They also freely swivel keeping your lines tangle free.

Pros

  • Strong and durable design
  • Easy to attach and detach with one hand
  • Freely swivels preventing tangles from being created

Cons

  • Larger than most attachment options
  • Has multiple moving parts that can become clogged with dirt and debris
