Door Threshold Product Highlights

 

The  door threshold  is made of aluminum alloy, waterproof and moisture-proof, wear-resistant, rust-resistant, not easy to fade, and ensures long service life.
Transition strips prevent carpet edges from fraying, and vinyl floor seams from curling, and create a smooth transition between different flooring surfaces.


Its easy installation process requires no special tools. Just stick it with glue. No need to punch holes and do not damage the floor.


It can be used on front doors, porches, or exterior entrances. Great replacement for PVC door straps, molding, caulk, etc.


You can tailor it freely according to your needs. The strip protects the tile edges with different levels.
