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.
Features
- Seals Around the Door – Closes off the gaps around the top and sides of a door so noise and air can’t sneak through.
- Boosts Door Performance – Achieves up to STC 46 when paired with a solid-core door with a threshold or sealed bottom.
- Customizable Seal – Fully adjustable design ensures a precise, airtight fit.
- Built Tough – Rugged aluminum housing with durable neoprene that stands up to years of use.
- Finishes to Match – Standard silver, with brown and gold also available. Call 1-800-679-8511 for quotes on custom colors.
- Simple to Install – Comes with all the hardware you need for a fast, no-fuss installation.
