Heavy Duty Thresholds

For areas where forklifts or vehicles operate,we recommend using heavy-duty thresholds designed to endure.

These thresholds, crafted from significantly thicker metal, are built to withstand heavier loads, ensuring a longer lifespan. They may resemble saddle thresholds in appearance but can also be equipped with bumper seals for enhanced durability and protection.

Bumper Seal Threshold

Bumper seal thresholds feature a seal at their top that contacts the door when it is shut. This design serves as a barrier for the door’s bottom, blocking moisture or airflow from passing underneath.

For these thresholds, the door’s undercut — the gap between the door bottom and the threshold — is a critical factor to consider for optimal sealing performance.

Saddle thresholds

Saddle thresholds, frequently utilized at exterior doorways, are a prevalent choice for creating a smooth transition. These thresholds may come with full-length supports underneath to enhance stability and durability.

The top surface of these thresholds can be designed as smooth, grooved, or even treated with special finishes. Such treatments aim to provide additional traction, reducing the risk of slips and falls by improving grip underfoot.

Carpet Divider Threshold

Carpet dividers serve an essential function in segmenting the flooring beneath doorways. They are versatile, capable of separating various flooring combinations such as carpet-to-carpet, tile-to-carpet, and concrete-to-carpet, among others.

These dividers are particularly crucial in fire-rated areas, where they prevent the spread of fire by blocking combustible flooring materials from facilitating fire travel underneath the door.
