This non-adhesive weather stripping is designed to fit slots ranging from 0.35 inch to 0.59 inch, with a total width of 0.57 inch that can be trimmed to exact required lengths for different sealing projects. Constructed with high density polyurethane foam coated with a smooth PU layer, the material resists high temperatures, abrasion, corrosion and impact, and will not deform easily after long term use. It works to fill gaps around doors and windows, block incoming dust and rainwater, reduce outside noise transmission, and create a more stable and comfortable indoor living space. No extra adhesive is required during installation, you only need to measure the target slot, cut the strip to proper size, clean the slot surface and press the strip firmly into place. It fits most sliding doors, security doors, screen doors, patio doors, glass doors, various windows, wardrobes and cabinet slots for wide household applications.
