Kason 1246 Reversible Cam-Rise Walk-In Door Hinge – Flush Offset

Kason 1246 Reversible Cam-Rise Walk-In Door Hinge – Flush Offset

The Kason 1246 Series is a reversible self-closing cam-rise walk-in door hinge designed for commercial cooler and freezer doors requiring a flush / 0-inch offset. The 1246 hinge uses a cam-rise action that lifts the door as it opens and allows it to settle toward the closed position as the hinge rotates.

Kason manufactures the 1246 Series from high-pressure die-cast zinc with a self-lubricating nylon cam. The design helps provide smooth door movement, reduce gasket drag, support reliable self-closing operation, and accommodate right- or left-opening walk-in doors.

This listing contains multiple finish options for the same Kason 1246 flush-offset hinge design. Select the exact manufacturer part number and finish required before ordering.

Available Kason 1246 Variants

• 11246000028 – Flush Offset – Polished Chrome
• 11246000040 – Flush Offset – Brushed Chrome
• 11246000004 – Flush Offset – Powder Coat

All three variants use the Kason 1246 reversible cam-rise hinge geometry with a flush / 0-inch offset. The primary difference between these options is the exterior finish.

What the Kason 1246 Cam-Rise Hinge Does

The Kason 1246 supports the walk-in door while providing controlled pivoting and self-closing action. As the door opens, the cam-rise mechanism raises the door slightly. As the door returns toward the closed position, the hinge allows the door to descend along the cam profile.

This cam-rise movement helps reduce gasket drag across the threshold and door frame while supporting smooth door operation and consistent closing performance.

Self-Closing Cam-Rise Design

Kason identifies the 1246 as an industry-standard self-closing cam-rise hinge. The self-lubricating nylon cam provides a smooth bearing surface inside the hinge while the cam geometry contributes to the closing action.

The design is particularly useful on commercial walk-in cooler and freezer doors where repeated opening and closing can place significant wear on hinges, sweep gaskets, and door hardware.

Reversible Right- or Left-Hand Operation

The Kason 1246 can be manually reversed for use on either right-opening or left-opening doors. This allows the same hinge series to be used across multiple walk-in door orientations when the required offset and mounting configuration match.

Always compare the original hinge orientation and mounting pattern before installation.

Door Hold-Open and Lift-Off Features

Kason specifies that the 1246 hinge can hold the door open beyond approximately 130 degrees. This can be useful during stocking, cleaning, equipment movement, and service.

The hinge design also allows compatible doors to be lifted off without disassembling or removing the hinges, simplifying certain service and maintenance procedures.

Why Cam-Rise Hinges Help Protect Door Gaskets

A walk-in door gasket can experience significant friction when the door drags across the floor or threshold during opening and closing. The cam-rise action lifts the door during opening, helping reduce gasket drag and wear.

Kason specifically notes that the cam-rise design helps reduce gasket wear even where floors are somewhat irregular.

Common Signs a Walk-In Door Hinge May Need Replacement

• Door no longer closes reliably on its own
• Door sags or sits unevenly in the opening
• Hinge binds during opening or closing
• Cam action feels rough or inconsistent
• Excessive play develops at the hinge
• Door sweep or gasket drags excessively
• Hinge body is cracked, bent, or physically damaged
• Mounting holes or hardware are worn
• Door alignment repeatedly changes after adjustment

These symptoms do not automatically mean the hinge itself is the only problem. Inspect the door, frame, latch, closer, sweep gasket, mounting hardware, and overall alignment before replacing components.

Technician Service Information

Before replacing a Kason 1246 hinge, inspect all hinges supporting the door. Uneven wear between upper and lower hinges can affect door alignment and closing performance.

Check the door for sagging or distortion and inspect the mounting surface for loose or damaged fasteners. A new hinge may not correct a door-alignment problem caused by damaged panels, loose mounting surfaces, or structural door issues.

After installation, operate the door through its full range of motion and verify smooth cam-rise action, proper self-closing movement, correct gasket contact, and acceptable door alignment.

Before You Order

Confirm that your application requires a Kason 1246 Series reversible cam-rise hinge with a flush / 0-inch offset.

Verify the following:

• Kason 1246 Series
• Exact manufacturer part number
• Required finish
• Flush / 0" offset
• Existing hinge mounting pattern
• Door handing and orientation
• Door and frame condition
• Existing hinge dimensions and geometry
• Condition of mounting hardware

Do not select a walk-in hinge based only on appearance. Kason manufactures multiple cam-rise hinge series with different offsets, sizes, mounting arrangements, and operating characteristics.

Frequently Asked Questions

What is the Kason 1246?
The Kason 1246 is a reversible self-closing cam-rise hinge designed for commercial walk-in cooler and freezer doors.

What offset does this Kason 1246 listing use?
The variants on this page are the flush-offset versions, which Kason specifies as a 0-inch offset.

Is the Kason 1246 reversible?
Yes. Kason designed the 1246 so it can be manually reversed for right- or left-opening door applications.

What is the difference between the three variants?
The hinge geometry and flush offset are the same. The manufacturer numbers identify different finishes: polished chrome, brushed chrome, or powder coat.

Does the Kason 1246 help the door close automatically?
Yes. The 1246 is a self-closing cam-rise hinge. The cam geometry helps the door return toward the closed position.

Can the Kason 1246 help reduce gasket wear?
Yes. Kason states that the cam-rise action helps reduce gasket wear by lifting the door as it opens, reducing drag across the floor or threshold.

Does the Kason 1246 hold the door open?
Kason specifies that the hinge holds the door open beyond approximately 130 degrees.

How do I confirm the correct Kason 1246 variant?
Verify the exact manufacturer part number, finish, flush offset, mounting pattern, door orientation, and existing hinge configuration before ordering.
