Door closers for controlled closure of walk-in cooler and freezer doors and other applications.
Flush Hook or Offset Hook – Flush hooks are used when the door is even with the frame when the door is shut. Offset hooks are used when the door juts out in further than the frame when the door is shut. The distance between the frame and the face of the door is the “offset”. Currently only flush and 1-1/8in offset hooks are manufactured, so any other door offset will require mounting to metal shims to align properly.
Concealed Mounting or Exposed Mount – Concealed mounting closers have a bracket that is screwed onto the door. The closer will attach to the base plate and will leave no visible screws. Exposed mount closers will often have tabs where screws are used to hold it in place. These screws will remain visible.
Base Plate – Screws that are drilled into foam may rip out, so many walk-in doors will have a metal base plate inside of the door that you can drill into. When replacing an old door closer, it is advisable to purchase a smaller or similar size closer and mount it in the same area so you make sure the closer attached to the base plate.
Dart – A protrusion that may be shaped like an arrow and pushes into a groove to secure the gasket.
Magnetic Gasket – A type of gasket that seals to the frame using magnets embedded inside of it. A magnetic gasket may be secured to the door with a dart or by some other method.
Wiper Gasket – On some models of walk-in, wiper gaskets will be found around the door and the frame to prevent air infiltration and icing. Customers sometimes refer to them as sweeper gaskets, not to be confused with a door sweep that is found at the bottom of the door.
Rain roofs are important for outdoor walk-ins to prevent water damage. We offer Duro-Last polyvinyl membrane roofs with all the mounting hardware and drip caps for the door. Measure the outer dimensions of your walk-in and choose from our standard sizes, or get a quote on a custom roof.
The Duro-Last membrane is a proprietary thermoplastic formulation that provides exceptional flexibility, reflectivity, resistance to U.V. radiation and flame retardance.
Roofing system performance is a balance between film formulation, membrane thickness and reinforcement. Duro-Last adds no “filler” material to increase the membrane thickness; their
film is the same proven formula from top to bottom. A key Duro-Last difference is the reinforcement scrim within the membrane. It’s a weft-insertion scrim with a density of 14 x 18 threads-per-inch which is among the highest in the industry.
