Fiber Optic Strand Lock Block

Get a Quote

This heavy duty fiber block is used for supporting a single fiber optic cable up to one inch dia. onto a maximum strand size of 3/8 in. (25mm) prior to lashing. Particularly recommended where a higher level of security is required such as crossing roadways or waterways. Always be certain to use enough blocks spaced close together to avoid any creation of cable sag. 

  • This block features the lever operated cam that locks the block in position while pulling, then automatically releases during lashing.
  • The frame is constructed from a heat treated aluminum alloy.
  • Oilite bearings on the sheave, and steel inserts on the underside of each strand hook allow the block to slide easily on strand for positioning.
  • A removable pin keeps the cable from jumping out of the sheave. Pin is tethered to the block to prevent losing it.
  • The frame hooks can accommodate strand from 1/4 in. to 3/8 in. (6-10m) diameter Weight: 3 lbs. 12 oz.
