This solid, heavy gauge, sound-rated door saddle with a neoprene gasket is great for sealing the gaps at the bottom of doors. The saddle fits under doors with a small gap clearance of 1/8” and up to 1/2" and features an enhanced neoprene bulb and finger gasket. The protruding rubber finger design ensures an airtight seal, even when the door is misaligned due to natural warping or poor installation. The saddle is smoke and fire-rated. The saddle is made of .125” thick aluminum and has passed the ANSI Standard Load Test to prevent bending and warping, even through constant usage. For extra protection (ideal for commercial traffic) Full Body Strength option is offered. Epoxy abrasives can also be applied to create a non-slip surface, ideal for environments where moisture is present.
