Product description
The Frost King TS36A Aluminum and Vinyl Sill Threshold is a replacement threshold for entry doors, especially pre-hung doors that originally came with a threshold. It combines a heavy-gauge aluminum exterior with a construction-grade vinyl interior, giving the doorway a durable sill surface while helping reduce cold transfer at the bottom of the door. Home Depot’s product details describe it as a fixed sill threshold with a low-rug design for heights up to 3/4".
This threshold is a practical option for residential door repair, weatherization, and draft reduction projects where the existing sill is worn, damaged, or no longer sealing correctly. The wider 5-5/8" profile gives more coverage than narrow saddle thresholds, while the 36" length fits many standard entry doors and can typically be cut to size during installation. Lowe’s also notes that this threshold is intended for screw installation and that maximum weathersealing is achieved when used with compatible door sweeps or door bottoms.
