Mullane 100S Snow Guards

Mullane 100S standard nail application snow guards are designed to be installed on slate and asphalt shingle roofs by nail application during the installation of the roofing. All BRONZE GUARD® products are cast in pure tin bronze, using only virgin metals to assure the highest quality alloy. The shoe is cast bronze and the strap is 24-ounce cold-rolled copper.

This is a traditional spike style snow guard from a design first patented in 1899. The Model #100 is historically accurate for period restorations, but is just as appropriate for new construction or retrofit application on existing slate roofs. Because of its low profile, this model is more appropriate for residential usage. The Model #100 is for applications on slate, shake, and shingle roofs, and is designed to fit between adjacent pieces of roof material, so that only the casting is visible above the roof surface.

Look at the photos for a side-by-side comparison of the Mullane 100S-NA and the Mullane 100S-AS. Use the #100-NA for thicker shingles. Check the CAD drawings below to make sure the dimensions work for your shingles.

This snow guard is also available in a retrohook style for installing on existing slate roofs. The #100 snow guard has a smaller face than the #200, and is less expensive. View the 200 standard.


100S-NA for Slate application - $13.50
100S-AS for Asphalt application - $13.50
