Door Draft Stopper 37" — One-Sided Cuttable Under-Door Seal for Drafts, Dust & Noise Cold air seeping under the door, dust settling on the floor, and outside noise bleeding into a room are all signs of an unsealed door gap. This door draft stopper installs on one side of the door with a velcro adhesive strip—no tools, no drilling, no permanent modifications. Made from Oxford cloth with a pearl cotton foam core, the stopper measures up to 37" (940 mm) in length and 3.5" (89 mm) in total height, with a 1.2" (30 mm) diameter foam tube sized for larger-than-average gaps. Cuttable to length for a precise fit. Available in white, brown, and black. Note: the white variant provides less light-blocking than brown or black. Use it to seal interior bedroom or living room doors against drafts and noise, block dust and insects under exterior or garage doors, or insulate bathroom doors to retain heat and reduce sound transfer. ✅ Fits doors up to 37" (940 mm) wide — works on carpet, tile, linoleum, and hardwood floors — interior and exterior doors ✅ Key Features of This Door Draft Stopper ✂️ Cuttable to Length: Trim to any width up to 37" with scissors for a precise fit on narrower doors—no leftover bulk or bunching at the edges. 🧲 Oxford Cloth + Pearl Cotton Construction: Abrasion-resistant Oxford cloth outer shell with a 1.2" diameter pearl cotton foam tube that compresses to fill larger-than-standard gaps under the door. 🔇 Noise Reduction: The foam core dampens sound transmission through the door gap—reduces noise from adjacent rooms, hallways, and outside. 🌡️ Draft & Energy Savings: Seals the gap that lets conditioned air escape and outside air enter—helps maintain room temperature and reduces heating and cooling load. 🧹 Dust & Insect Barrier: Closes the under-door gap that allows dust, dirt, and small insects to enter—keeps floors and rooms cleaner between cleanings. 📌 Velcro Adhesive Mount: Peel-and-stick velcro strip attaches to the door face—moves with the door on any floor surface, removable without damage to the door finish. 🎯 Who Is This For? 🛌 Bedroom & Living Room Doors Block cold drafts and reduce noise from hallways or adjacent rooms—install in minutes without tools and remove cleanly when no longer needed. 🏚️ Exterior & Garage Doors Seal the gap under exterior doors and garage entries to keep out dust, insects, and outside air—the Oxford cloth outer layer handles the abrasion of daily door movement. 🛁 Bathroom & Utility Doors Retain heat in bathrooms and reduce sound transfer from utility rooms—the foam core fills uneven gaps and the velcro mount stays secure on tile and hardwood floors.

Yes. The stopper can be cut to any length up to 37" using scissors. Measure your door width, mark the stopper, and cut straight across. The Oxford cloth edge does not fray significantly after cutting. Will the velcro adhesive damage my door finish? The peel-and-stick velcro strip is designed to be removable without damaging the door surface. Peel slowly and evenly when removing. On painted or varnished doors, test a small area first if the finish is older or fragile. Does this work on carpet floors? Yes. The stopper moves with the door as it opens and closes, gliding over carpet, tile, linoleum, and hardwood without scratching or snagging. The foam tube compresses slightly to maintain contact with uneven floor surfaces. What is the difference between the white and dark color options? All three colors—white, brown, and black—provide the same draft, dust, and noise sealing performance. The white variant provides less light-blocking than brown or black. If blocking light under the door is important, choose brown or black. Is this suitable for exterior doors? Yes. The Oxford cloth outer layer is abrasion-resistant and handles the wear of daily door movement on exterior and garage doors. It blocks dust, insects, and outside air effectively. For heavy rain exposure, check that the adhesive strip remains secure periodically. How thick of a gap will this seal? The 1.2" (30 mm) diameter foam tube is sized for larger-than-standard gaps. It compresses under the door to fill gaps of varying sizes. For very small gaps (under 0.25"), a thinner door sweep may be a better fit. 🛒 Select your color above, then add to cart.
