The Model FR132 Snow Fence Bracket is cast from solid bronze for lifetime durability. The castings have been carefully engineered to assure maximum strength at the points of the greatest stress when under load. All parts are cast in foundries in the USA, assuring that only pure alloys are used in their manufacture. Holes for rails are 1.125” to accommodate 1.05” (OD) brass pipe. The brackets are adjustable to various roof pitches.
Uses, Application: Typically installed along the perimeter of slate 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 bronze. The tin bronze alloy is the most durable material for this application, will not crack, and will weather to a pleasing patina over time. The castings are riveted to the base assembly using solid copper rivets. Testing has shown the rivets remain secure at over 4000 pounds of direct force. The base plate is 1/8” commercial bronze or brass plate, sized to the slate dimension, and predrilled and countersunk for fasteners. Bolts are solid brass.
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 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 model #100s or #200s snow guards.
Our Technical Services can provide a spacing recommendation upon receipt of a roof plan, showing rafter lengths, and necessary elevations for roof pitch.
