FK-501 FA1 3 m Webbing Self-Retracting Fall-Arrester Block
Self-Retracting Lifelines / Fall-Arrest Blocks (EN 360)

The FK-501 FA1 is PGTEC's entry-level 3 metre webbing self-retracting lifeline, certified to EN 360 and designed for operators who need immediate fall protection close to the anchor point on short work fronts such as steel erection, mezzanine edges, elevator shafts and scaffolding tie-off positions. The compact navy-blue engineering-polymer housing with brushed aluminium side plates encloses a spring-loaded drum that pays out and retracts a flat woven polyester webbing tape at walking pace, while a centrifugal braking mechanism locks the tape within a few centimetres of any sudden acceleration, keeping arrest distance to under 0.4 m and peak arresting force below 6 kN on the user's body. A forged galvanized steel snap hook with double-action gate and a swivel top anchor ring make connection quick and intuitive, and the low 700 g mass means the block can be worn on a dorsal harness attachment or hung from a fixed anchor without fatigue. Webbing construction gives the FA1 a soft, snag-free profile that does not scratch finished steel or glass facades, and the transparent wear indicator on the webbing makes pre-use inspection fast. Typical users include scaffolders, steel fixers, maintenance technicians, warehouse order pickers on mezzanines and HVAC installers working near unprotected edges. PGTEC supplies the FA1 with a user manual in five languages, a 5-year manufacturer warranty and full batch traceability, making it a practical, cost-efficient first point of protection for any short-fall working-at-height task where a full-length SRL would simply be over-specified.
