About the Blocfor™ 20 Fall Arrester:

The Blocfor™ 20 Fall Arrester offers options for a 20m galvanised, stainless steel or synthetic rope.

The synthetic version of blocfor™ 10 AES, 20 and 30 enables them to be used
for specific applications (electrical environment, petroleum fumes, restricted
spaces, white rooms, etc.). The aramid fibre synthetic cable avoids the use
of the webbing lanyard for terrace work.
