This non-adhesive weather stripping is designed to fit pre-cut slots ranging from 0.35 inch to 0.59 inch, with a total width of 0.57 inch that supports easy customization to match exact slot length requirements. Constructed with high density polyurethane foam wrapped in a smooth PU coating, the material resists high temperatures, abrasion, corrosion and regular impact without permanent deformation, for extended daily use across different indoor and outdoor fixtures. It fits seamlessly into the side grooves of sliding doors, security doors, screen doors, patio doors, glass windows, wardrobes, closets and cabinets, effectively filling gaps to block incoming dust, moisture and outside noise. Installation requires no special tools, just measure the target slot, cut the strip to the exact needed length, wipe the slot clean and dry, then press the strip firmly into the groove for a secure fit that improves overall indoor comfort.
