Technical Details

I acquired this International Safety Components Keeloc SmartSnap™ RP420 from Fallout Bunker in 2024.

My SmartSnap™ RP420 is 164 mm. long, 152 mm. wide, 20 mm. high, and weighs 322 g.

The SmartSnap™ RP420 consists of a milled and hard-anodized aluminum alloy body with carabiner gates on each side. Stainless steel liners help protect the top of the carabiner openings from wear. A blocking mechanism hidden behind a screw-attached cover moves laterally to ensure that one gate is blocked from opening at all times. To slide the gate to one side, one must insert a pin into an opening behind the plate on the side of the gate one wishes to lock. The mechanism prevents sliding the blocking slide directly.

A 25 mm. wide, 13 mm. attachment eye is at the bottom center of the SmartSnap™," Manufactured in uk by I|S|C," "191097840073," "CE0120," and "EN362:04T."

Comments

The SmartSnap™ is designed for use on ropes courses where 100% attachment is required. The SmartSnap™ ideally allows the user to traverse all of the individual elements of a course without ever being able to detach from the safety line. It was presumably designed for people who cannot be trusted not to be stupid enough to unlock their safety (e.g., the general public).

The SmartSnap™ requires a key for proper operation. There are two standard keys: a Ring Key and a Wire Key.

The User starts with the SmartSnap™ attached to their harness with a tether. They approach the first cable and clip the unlocked side of the SmarSnap over the cable. Under supervision, they then lock that side of the SmartSnap™ using the Wire Key attached to the cable. They then proceed to the other end of the cable.

When reaching the other end of the cable, they use a tethered Ring Key to unlock the SmarSnap from the cable. The Ring Key only fits if it is positioned to be captured by the SmarSnap. Unlocking the cable side will lock the Ring Key side. The user is now protected by the ring key and tether.

At this point, the user moves the SmartSnap™ to the next cable and locks it in place with a Wire Key attached to that cable. This releases the Ring Key, allowing the user to move along while protected by the new cable.

Upon reaching the end of the course, staff members can unlock the SmartSnap™ using a loose Wire Key or similar tool.

While not perfect, the system provides considerable idiot-proofing - but the Universe is developing more sophisticated idiots every day.
