Thermwell PD84CL Patio Door Weather Strip 1.87x84 in

Product Description

The THERMWELL PD84CL is a self-adhesive patio door weather strip designed to seal the center post gap between sliding glass door panels. Also referred to as a center post weather strip, this product closes the contact point where the movable slider meets the stationary panel, blocking the passage of air, dust, and insects. The strip measures 1.87 inches wide by 84 inches long, making it compatible with standard full-height patio door openings. Installation requires no tools — the peel-and-stick backing adheres directly to the movable slider panel. This product is installed by contractors, handymen, and property maintenance professionals during door weatherization service or seasonal prep work.

This weather strip is suited for residential sliding patio door applications where the center post or meeting rail area is allowing infiltration. It addresses a common failure point in older or worn sliding door assemblies where the original factory seal has compressed or deteriorated. The 84-inch length accommodates most standard residential patio door heights. The self-adhesive design allows for quick field installation without fasteners, adhesive compounds, or specialty tools. A package quantity of 8 units makes this product practical for multi-unit residential work or stocking service vehicles.

Installation Notes

Installation is performed by general contractors, property maintenance technicians, or experienced DIYers. Clean and dry the application surface on the movable slider panel before removing the backing paper to ensure proper adhesion. Peel the backing paper from the strip and press firmly along the full length of the slider in a single pass. No power tools or fasteners are required, but surface prep is critical for long-term adhesion in exterior door environments.
