ISC has further developed its range of fall arrest rope grabs by improving function.
A low cost compliance device has also been added.

ISC manufactures a pair of high quality, low weight rope grabs which are machined from 6082 aluminium & hard anodised. The small device is suitable for use on 11 - 13mm diameter semi static ropes, whilst the largest device is suitable for 13-16mm diameter semi static ropes. Tests reveal some differences in performance due to different rope specs & environmental conditions. tearing of the rope sheath can occur with some kernmantle ropes.

Each device has a choice of axle types.

		RP203 > Small. RP204 > Large. Fixed/Bolted version can only be fitted by threading the rope into the device from the end.
		RP201 > Small RP206 > Large. R-clip version can be fitted to the rope at any point by way of an R-Clip which is pushed into the axle nose.
		RP209 > Small. RP205 > Large. Pip pin version can be fitted to the rope at any point. The axle is fitted or detached by pushing on the thumb button to release the locking Bearings.
