Sound Lock™ Door Jamb Seals
Sound Lock™ Door Jamb Seals close the gaps around the top and sides of a door with a threshold or bottom door seal. These jamb seals create an adjustable, airtight fit that stops sound and plugs drafts. With durable aluminum and long-lasting neoprene, they turn a solid-core door into a much more effective sound barrier.
