For efficient tie down to concrete masonry.

BlockFast is a fast and simple installation system for holding down roof trusses to masonry block series 150, 200 or larger. They are used to tie down roof trusses to bond beams in masonry walls to resist very high uplift.


  • Easier and faster than heavy steel cleats, BlockFast straps can be slipped into place in any number of ways and do not require pre-drilling or bolting.

  • The BlockFast loop holds the strap in place onto the rebar and a clasp to facilitate installation.

  • For additional uplift capacity, a pair of BlockFast straps may be located on both sides of the truss.

  • Target rings on the BlockFast strap help the user aim and accurately locate gun nails.
