The L-Mount® attachment, featuring an open-slotted L-Foot, is designed for cost-effective, single-bolt installation onto existing composition (asphalt) shingle roofs. The patented Elevated Water Seal Technology® has been integrated into the open-slotted L-Foot and flashing for fast installation, to provide maximum waterproofing.  

To maximize versatility, the attachment kit is available with a lag bolt or structural screw option—meaning it can work with all side-mounted racking in the market. Both hardware options come with an installed EPDM bonded washer to seal and prevent water entry. 

The redesigned L-Foot can rotate 360 degrees for optimal adjustability and positioning of the rail, while the open slot allows the rail hardware to quickly drop-in. L-Mount® also features a 9×12” aluminum flashing with alignment guides and rounded corners, to easily slide under shingles and speed up installation on the roof. The kit is available in both mill and black finishes.
