"Reducing stress, simplifying processes and generally making the restraint process easier for everyone provides measurable value for all involved — officers and people in crisis."
Automatic Double Lock (ADL)
The patented ADL system mechanically prevents overtightening — automatically. No manual step required. No forgotten locks. No neuropathy.
The bail is up to 63% wider than competitor handcuffs, distributing force more effectively across the wrist to reduce pressure points.
Six patented innovations working together to make restraint safer, faster, and easier — for officers and subjects alike.

Core Safety Innovation
Automatic Double Lock (ADL)
Handcuff neuropathy — nerve damage caused by overly tight handcuffs — has plagued law enforcement for over a century. Traditional handcuffs require a manual double-lock step that is routinely forgotten, improperly applied, or impossible during a struggle.
SpiderCuff's patented ADL is a mechanical system activated by wrist pressure that locks against reverse-facing teeth, preventing the cuff from tightening beyond a safe point. It engages instantly upon deployment — no manual step, no keys, no second action. This is the only handcuff with a built-in mechanism that automatically prevents overtightening beyond the injury risk threshold.
Model 01 extends up to 14 inches for dual-wrist restraint application. This allows officers to cuff at distance rather than close range, fundamentally changing the dynamics of deployment.
A one-way ratchet is triggered — stopping the struggle — as arms move easily into position with mechanical advantage. University of Massachusetts research confirms a 49% reduction in shoulder force compared to standard methods. The three-step process is simple: Click → Extend → Click.
Arms-at-the-side deployment becomes possible, reducing force, stress, and eliminating the need for a second set of handcuffs for larger individuals. Dynamic Extension does the job of two or three traditional restraints.
SpiderCuff's asymmetrical pistol grip design combines the flexibility of chain handcuffs with the directional control of hinged cuffs — the best of both worlds in a single device.
The grip provides superb control under stress, allowing intuitive single-handed deployment. Rounded edges eliminate sharp contact points that cause injury during application, and the ergonomic form reduces officer fatigue during extended carry.
Pistol grip — chain flexibility meets hinged control
Injury Prevention
63% Wider Bail
SpiderCuff's bail (the curved portion that contacts the wrist) is up to 63% wider than any competitor handcuff. This wider surface area distributes restraint force across a larger area of the wrist, dramatically reducing pressure points.
Combined with the wide body design, this makes overrides — where a subject forces their hand through the cuff — nearly impossible, improving security while reducing the risk of wrist injury.

Security
Finger-Activated Triple Lock
SpiderCuff features a finger-activated secondary lock that functions as a manual "triple" lock (in addition to the automatic double lock). No key is required — the officer simply engages it with a finger press.
This provides three layers of lock security: the primary ratchet lock, the automatic double lock (ADL), and the finger-activated triple lock. An integrated anti-pick deterrent further secures the mechanism. Despite all this, SpiderCuff remains compatible with standard handcuff keys.
Every SpiderCuff is built with anodized aluminum exterior and corrosion-resistant internals. This delivers significant weight savings — the Model 10 is approximately 20% lighter than standard steel handcuffs — without sacrificing strength.
The cord (connecting chain) exceeds 1,000 pounds of tensile strength, more than twice the NIJ requirement. The Model 40 variant is specifically engineered for prolonged life in wet and marine environments, with enhanced corrosion resistance throughout.
All models meet or exceed NIJ Type 3 restraint classification standards.
Only SpiderCuff handcuffs automate safety. Three models engineered for the demands of modern law enforcement and corrections.

Type 3 restraint classification
What is NIJ Type 3? — The National Institute of Justice classifies restraints by capability. Type 3 includes devices with extended reach and integrated safety mechanisms, exceeding the standards of traditional chain (Type 1) and hinged (Type 2) handcuffs.
The flagship SpiderCuff with Dynamic Extension technology — up to 14 inches of reach for safer, easier restraint application.
Dynamic Extension
With up to 14 inches of dynamic extension, Model 01 reduces force by 49% — thereby de-escalating deployment. A one-way ratchet is triggered, stopping the struggle, as arms move easily into position without force or resistance.
The pistol grip design provides control similar to hinged handcuffs while the extension capability allows restraint at distance — keeping officers safer.

SpiderCuff Certified Transition Training is recommended. Let's discuss how to incorporate it into your training programs.
Designed to make the life of a Corrections Officer easier and safer — less altercation means fewer injuries for everyone.
Easier & Safer Deployment
SpiderCuff is designed to make the life of a Corrections Officer easier and safer. The extended range of deployment for Type 3 restraints facilitates easier application, reduces effort, and accelerates the process — helping address struggle and conflict.
Less of an altercation means fewer injuries — for everyone involved. Truly a win-win. The product will be available in various size models.
Transport
SpiderCuff technology is practical for prisoner oversight during transport, streamlining the process and reducing risk during movement.
ADA Compliance
The ADA increases responsibility for those managing individuals with disabilities. SpiderCuff provides flexible deployment options to accommodate diverse needs while maintaining security standards and officer safety. Multiple deployment points offer flexibility for varying circumstances and physiological considerations that traditional handcuffs cannot address.
Multiple levels of training designed to serve law enforcement agencies transitioning to SpiderCuff technology.
