The L-Mount is designed for cost-effective, one-bolt installation onto existing composition/asphalt shingle roofs. The patented Elevated Water Seal Technology® has been integrated into an L-foot and flashing for fast, single-lag bolt installation with unparalleled waterproofing.

L-Mount comes with lag bolt or structural screw attachment options for maximum versatility and works with all leading racks. The L-foot can be rotated 360 degrees for optimal adjustability and positioning of the rail.

L-Mount also features a 9 x 12-inch aluminum flashing with alignment guides and rounded corners to easily slide under shingles and speed installation on the roof. Available in aluminum mill and black finishes.
