Chalfant has pioneered the development of dock seal technology that protects, buildings, products and employees from the entry of wind, water, snow, dust and dock fumes, which results can be seen in energy savings. And now, with the patent pending Guardian 3-in-1 Dor-Seal System, we have added another important beneu001ft; security.


The Guardian 3-1 Dor-Seal System unique triple duty design, keeps conditioned air and packages in and keeps people out. Let your unattended dock be a safe experience againstthieves, who can cut through an ordinary foam core of a dock seal. The Guardian 3-in-1 Dor-Seal System can prevent unauthorized entry and is available with three basic selectable features;

1. Chain-Link Cladding...

Vinyl coated chain-link structure surrounds the foam padding to keep thieves from cutting through the pad to gain access to the trailer and your facility.

2. Unique Mounting Plate...

Heavy-duty wood or optional steel substructure lends stability and rigidity to the dock seal and provides a strong, secure connection to the mounting brackets.

3. Foam Backing...

Soft foam conforms to irregularities of building walls, providing an air and water -tight seal between the dock pad and the building wall

Chalfant dock seals are factory assembled and mounted to kiln dried 2” wood and feature “Weathertight Construction” completely encased inside ofthe pad coverto protectitfrom abuse and outside elements. Galvanized steel mounting brackets are available in various sizes for diu001eerent types of building applications and types of pads. All brackets are bolted to the dock door frame. The Dor-Seal pads are positioned in the brackets and attached with lag bolts providing a secure connection to the building and allows quick removal of old units and install of new.
