Magnetic Door Gaskets for Kolpak Walk-Ins – Size & Handing Options

Magnetic Door Gaskets for Kolpak Walk-In Coolers and Freezers – Multiple Sizes and Hinge-Side Options

These magnetic replacement door gaskets for Kolpak walk-in coolers and freezers are available in multiple sizes and door configurations. Select the gasket that matches your existing seal's dimensions, mounting profile, hinge-side arrangement, and number of sides.

This listing brings the available gasket options together in one place. Your selection determines the gasket supplied. Left-hinged and right-hinged versions are separate configurations where offered, and matching dimensions alone do not establish interchangeability.

Available Gasket Sizes

The following sizes cover the selections in this listing. Some sizes have separate left-hinged and right-hinged options. Choose the complete size and configuration required for your door from the selection menu.

Separate left-hinged and right-hinged selections are offered at 32-1/4 x 75-1/4 inches, 36-1/4 x 77-1/4 inches, and 38-1/4 x 77-1/4 inches. For every size, confirm the complete configuration before ordering. A selection without a hinge-side designation should not be assumed to fit both directions.

The product photographs and drawing show the gasket cross-section, not the full assembled gasket. Profile measurements describe the sealing section and mounting stem; they are not the overall width and height selected for your door.

Magnetic Sealing and Hinge-Side Configuration

The magnetic sections help hold the flexible sealing face against the door's mating surface when the door is closed. Correct gasket seating and door alignment are important for even contact around the intended sealing perimeter.

Magnet placement can differ by configuration. Certain walk-in gaskets use a foam-filled section on the hinge side rather than a magnetic section. Do not assume every side contains a magnet or that left-hinged and right-hinged versions can be substituted.

How to Identify Door Handing

Stand outside the walk-in and look at the closed door. Hinges on your left indicate a left-hinged door; hinges on your right indicate a right-hinged door. Compare that orientation with the original gasket's hinge-side construction and the selected replacement.

Before You Order

• Match the exact gasket dimensions: Measure the original gasket without stretching it and confirm that the replacement uses the same measurement reference points.
• Compare the mounting profile: Check the sealing face, flexible section, mounting stem, and retaining channel against the original gasket.
• Confirm the hinge side: Select the correct left-hinged or right-hinged configuration where specified.
• Verify the number of sides: Confirm whether the required gasket is three-sided or four-sided. Do not apply one configuration's side count to every size in this listing.
• Check the magnetic arrangement: Match any foam-filled or non-magnetic hinge-side section.
• Match the correct part reference: Any manufacturer number must correspond to the specific size and configuration being ordered, not simply to the Kolpak brand.

Door-opening dimensions, door-panel dimensions, and gasket dimensions are not interchangeable. When the original gasket is missing or distorted, use the equipment model, serial number, door information, and profile photographs to confirm the replacement before ordering.

When to Inspect the Existing Door Seal

Inspect the gasket when you notice torn corners, split sealing sections, flattened areas, separation from the mounting channel, or uneven contact with the frame. Check the mounting channel and mating surface for damage or buildup.

Also inspect the hinges, latch, door closer, and door alignment. Replacing a gasket alone may not correct a sagging door, damaged retainer, or misaligned latch. After replacement, check that the gasket is seated evenly and that the door closes and latches correctly.

Gasket Care

Kolpak recommends monthly inspection of the door hardware, gasket, jamb, and sweep gasket. Clean magnetic door gaskets regularly with a mild detergent, remove soap residue, and dry thoroughly with a clean cloth. Do not use a high-pressure hose to clean the walk-in.

Frequently Asked Questions

How do I choose the correct gasket option?

Match the listed gasket dimensions, mounting profile, hinge-side arrangement, magnetic configuration, and number of sides. Choose the complete option required for your door rather than selecting the closest size.

Why are there left-hinged and right-hinged options at the same size?

The hinge-side construction or magnetic arrangement can differ even when the overall dimensions match. Select the configuration that matches the original gasket and door.

How do I determine the hinge side?

View the closed door from outside the walk-in. Hinges on the left indicate left-hinged; hinges on the right indicate right-hinged.

Are all options three-sided gaskets?

Do not assume the same side count across all sizes. Confirm whether the selected replacement requires three-sided or four-sided construction and compare it with the original gasket.

What do the measurements in the product images mean?

The illustrated 11/16-inch top width, 1-1/8-inch height, and 3/16-inch mounting stem describe the gasket cross-section. They do not describe the overall gasket size selected for your door.

Does one manufacturer part number apply to every option?

No. Manufacturer references must be matched to the individual gasket configuration. A reference associated with one size and hinge direction should not be used to identify every selection.

Does an option without a hinge-side label fit both directions?

Not necessarily. Confirm its magnetic arrangement, side count, and intended door configuration before ordering.

Will a new gasket fix every door-sealing problem?

No. Check the door alignment, hinges, latch, closer, mounting channel, and frame contact surface. These components must work correctly for the gasket to make consistent contact.
