Heavy-Duty Aluminum Construction

Built for exterior applications, the aluminum construction provides strength and long-term durability while standing up to frequent foot traffic and changing outdoor conditions. The grooved threshold surface provides a clean, professional appearance suitable for replacement projects and new installations.

Adjustable Design for a Better Door Fit

The adjustable configuration helps accommodate variations between the bottom of the door and threshold. This makes it easier to achieve proper contact at the doorway and improve the overall fit of the exterior door system.

Built-In Seal for Weather Protection

A built-in PVC insert helps create a secure seal beneath the door. The design helps reduce drafts and provides additional protection against rain, wind, dust, debris, and insects.

A properly fitted threshold can also help reduce unwanted air movement around the bottom of an exterior door, supporting better indoor comfort and energy efficiency.

Residential & Commercial Applications
