Mullane Fitrite #131ML 3-Pipe Galvanized Snow Rail Bracket for slate roofs. 

The Model #131 Snow Fence Bracket is cast from malleable iron and zinc plated for durability. The castings have been carefully engineered to assure maximum strength at the points of the greatest stress when under load.

The brackets are adjustable to various roof pitches.

Install snow fence bracket parallel to the eaves, 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. 

The base plate is 11-gauge galvanized steel, sized to the slate dimension (select size below), and pre-drilled and countersunk for fasteners. Bolts are grade 5 zinc-plated steel.

Snow rails are used along the perimeter of slate roofs for the prevention of sudden and unexpected ice and snow avalanches, which can damage people, cars, shrubbery, lower roofs, and other property underneath. The rail system can also include stainless steel expanded metal to prevent slates and other debris from sliding under the rails and creating a hazard. Also, a standard field array of snow guards can be included on the field of the roof above the snow rail for maximum protection.

Snow rail fence brackets are installed parallel to and approximately 24-36 inches above the eaves. The brackets should be spaced from 18-24 inches to no more than 42-48 inches apart horizontally, depending on the pitch of the roof and the expected snow load. It is recommended to use through bolts with a backer plate on the underside of the roof deck. Bronze, brass, or stainless steel pipe is recommended. Copper water pipes should not be used with Mullane snow rails, although they are used with Sieger snow rail brackets, both for 
slate roofs and for standing seam roofs

High snow load areas should use a three-pipe system such as the Mullane 500, the Mullane Fitrite 131 ML, or the Mullane Fitrite 132 BR,  If a smaller system is used, then it should be supplemented with an additional snow guard array in the field of the roof above the snow rail.
