So innovative, so advanced...it's simple. Go as fast as you need to; as fast as you want. But no faster. Sterling Rope's new F4 auto-locking escape device gives firefighters an advanced, yet remarkably simple tool for emergency egress from a rapidly worsening structural fire. Or it can offer tactical operators, SWAT, or military personnel an option for a quickly improvised escape if a tactical situation suddenly turns bad.

Lighter, smoother, less complicated. Sterling's goal was to build a better descent device— one that would deliver maximum advantage from their line of industry-leading escape ropes, such as the FireTech 32™. The F4 was designed and developed in-house, then tested and refined with assistance from veteran firefighters and instructors in departments all across the country. The F4's sleek, low-profile body is machined from lightweight, ultra-strong 6061 aircraft grade aluminum with a smooth, hard-anodized finish that allows the rope to pass through easily and without abrasion. At only 6 oz., it's hardly noticeable in your bailout bag...or your hand. Yet the F4 can stop or control the descent of over 300 lbs. of firefighter and gear. And with just one moving part (not counting the rope), this patent-pending device combines the simplicity of a figure 8 descender with the added safety and mechanical advantage of much more complicated auto-locking descenders.

Auto-locking descent control for maximum safety. The F4 is engineered for fast action and reactive safety, even in the most stressful situations. Proper training is required, of course— and necessary to build and maintain confidence. But once familiar with this unique escape device, operation is so simple it's virtually instinctive.

Single-handed horizontal movement. The F4 is designed to allow easy horizontal movement towards the point of egress. Simply squeezing the lever allows the rope to play through smoothly and quickly, for fast movement from the anchor point to your chosen egress.
Hands-free edge transition. The auto-locking feature adds security and confidence for a hands-free bailout. Once at the window or egress point, pulling a few extra feet of rope through the device provides some play. Then simply letting go of the device engages the auto lock, and allowing the escaping firefighter both hands free to climb through the exit point without fear of falling.
Hands-on descent. Once safely through the egress, and ready to descend, the operator can grip the F4 in one hand, and the free end of the rope in the other, to begin a, controlled rappel to safety. The fire fighter must use both hands to operate the F4 and rope. The brake hand controls the speed of descent.
Hands off to stop. Just release the lever to activate the brake. This is both a safety and a fail-safe. An unconscious or injured firefighter who is unable to maintain pressure on the lever will stop automatically—preventing a dangerous fall and providing time for a rescue.
