The Beamer 2000+ has the same durable aluminum and bronze construction as our popular Beamer 2000, but adds a swivel D-ring (to help reduce tangles), and the release mechanism has been moved to prevent accidental contact. It is compatible with overhead or foot-level applications, and it accomodates beams from 3 1/2" to 14" wide with flanges up to 1 1/4" thick. Note: When used at foot level, a Guardian Fall Protection Big Boss Extended Free Fall Lanyard must be used.
