The Model 231 Snow Fence Bracket is cast from solid aluminum for lifetime durability. The castings have been carefully engineered to assure maximum strength at the points of the greatest stress when under load. Holes for rails are 1.125” to accommodate 1.05” (OD) galvanized pipe. The brackets are adjustable to the roof pitch.

Uses, Application: Typically installed along the perimeter of low slope roofs to prevent the sudden and unexpected sliding of snow. When used in combination with individual guards (Field Array), it offers the greatest protection against any sliding of accumulated snow or ice, and the subsequent damage.

Materials: Bracket is solid cast aluminum. The assemble Base is integrally cast to the mounting plate, which is 1/4" thick aluminum. Mounting Plate is predrilled and countersunk for fasteners. Parts B and C, the pipe holder and strongback brace, are cast malleable iron, zinc plated. Bolts for assembling parts B and C are solid zinc.

Installation: Install snow fence bracket parallel to the eave, spacing the brackets from 24” to no more than 48” apart, depending upon the pitch of the roof and the anticipated snow load. Install brackets approximately 24” to 36” from the roof edge.

Recommended installation method is to use through bolts, with a backer plate on the underside of the sheathing. The use of galvanized, bronze, brass or stainless steel pipe or rod is recommended. Copper water pipe is NOT recommended.

In high snow load, and a rafter of over 25’, a second row of fence is recommended. As an alternative, or in areas where ice slides are possible, supplement the fence system with an array of spike or pad style snow and ice guards.

Our Technical Services can provide a spacing recommendation upon receipt of a roof plan, showing rafter lengths, and necessary elevations for roof pitch.
