Mullane 300S-RH Retrofit
Mullane 300S-RH copper/bronze retrohook style snowguard for installing on existing roofs. The solid bronze casting eliminates the corrosion problem caused by condensation which is formed inside of closed, pressed copper snow guards. The installation flange can be easily fabricated to any length for any roof application.
18 inches long, 2.5 inches wide, protrudes up from the roof about 2 inches. The half round Model 300 casting is attached to a 20 oz. copper installation base flange by four brass rivets for extreme durability and snow load bearing capacity. The solid bronze casting is extremely durable and rugged, testing at 870 pounds pressure.
This snowguard has a "reach" of about 13.5 inches. It can slide up underneath the slates 13.5 inches maximum before engaging the top of the underlying slate. So for a typical 24 inch long slate with a 3 inch headlap and a 10.5 inch exposure (13.5 inch unexposed), the snowguard should just have enough reach to slide underneath, slide the length of the unexposed area, and hook over the top of the slate. Shorter slates will leave more of the snowguard exposed. One advantage to this snowguard is that you can install it over the head of slates on random width roofs and still maintain a uniform layout on the snowguards because you don't have to line the snowguards up with the slots.
