Massif Steel Timber Truss Plates for 6"–10" Wide Timbers

The Massif Collection is a line of broad timber truss plates for timbers 6" to 10" wide. Named for the mountain massifs, its plates are a uniform 6" wide on the perimeter timbers and on the webs inside the truss, which gives a timber frame a bold, solid look. The smallest size is an actual width: a Massif plate won't fit a surfaced 6x6, which is only 5 1/2" wide.

Every plate a truss needs is here: king post, peak, heel, collar tie, strut, fan, and strut fan truss plates, a ridge beam truss saddle, and T, corner, and splice plates. Each is laser cut from 3/16" or 1/4" steel at roof pitches from 3/12 to 12/12, with 11/16" holes for 5/8" bolts unless you choose another size. Plates ship unfinished; add matte black powder coating in the cart. Shipping is free in the lower 48 states.
