ISC RAD Rope Adjustment Device


The ISC RAD ‘Rope Adjustment Device’ is a multi-functional device which can be used as part of a work-positioning lanyard (for 10.5 – 12.7mm rope). The RAD can also be used for ascent, descent, work positioning/restraint, belay and progress capture. The ‘squeeze style’ device makes smooth adjustment easy, while the spring-loaded flip down handle allows easy use, especially in descent mode.

The RAD can be supplied as an individual device* which can be fitted with rope and a choice of connectors. The ISC RAD now features a new top bollard, which allows the user the choice of fixing the side plate in place (in line with Lanyard related standards), or removing the captivation screw, allowing the front plate to be swung open. The swinging side plate is particularly useful when the device is in used in descent/ascent.
