Kason 11249000004 OEM 1249 Spring-Assisted Cam-Rise Hinge

Kason 11249000004 OEM 1249 Spring-Assisted Cam-Rise Hinge

The Kason 11249000004 1249 Series Hinge is a genuine Kason spring-assisted cam-rise hinge designed for commercial walk-in cooler and freezer doors. This exact configuration is identified by Kason as a right-hand, flush-offset, polished-chrome hinge.

The 1249 Series combines spring-assisted closing force with a high-lift cam system that helps move heavy walk-in doors through their normal opening and closing cycle. Proper hinge operation supports door alignment, gasket compression, latch engagement, and reliable walk-in cooler or freezer access.

When inspection confirms hinge replacement is required, using the correct Kason manufacturer part number 11249000004 helps preserve the intended spring, cam-rise, offset, finish, and mounting configuration of the original door hardware.

What the Kason 1249 Hinge Does

The Kason 1249 Series hinge supports the walk-in door while allowing it to pivot smoothly between the open and closed positions. Its spring mechanism provides additional closing force, while the cam-rise design lifts the door during opening and allows it to settle toward the closed position as the hinge rotates.

Proper hinge operation helps support:

• Smooth walk-in door movement
• Reliable spring-assisted closing
• Proper door alignment
• Consistent gasket compression
• Reduced gasket wear
• Reliable latch and strike engagement
• Reduced threshold dragging
• Dependable commercial refrigeration door operation

Spring-Assisted Closing Force

Kason designed the 1249 Series with an internal spring mechanism that provides additional closing force for heavier walk-in doors and applications where air resistance can make reliable door closure more difficult.

This spring assistance works together with the cam-rise mechanism rather than functioning as a separate external door closer.

High-Lift Cam-Rise Design

The 1249 uses Kason's high-lift cam system. As the door opens, the hinge raises the door through the cam profile. As the door returns toward the closed position, the cam allows the door to settle back into its intended sealing position.

This action helps reduce gasket drag and wear, particularly where floor conditions or door alignment are less than perfect.

Built-In Hold-Open Beyond 130°

Kason specifies a built-in dwell that holds the door open when moved beyond approximately 130 degrees. This can help during stocking, equipment movement, cleaning, and walk-in service.

The door should still be evaluated for correct hinge operation and surrounding clearance before relying on the hold-open position.

Right-Hand, Flush-Offset Configuration

Kason lists 11249000004 as a right-hand hinge with flush offset. The flush configuration means the hinge is designed around a 0" offset relationship for the applicable door and frame arrangement.

Kason's 1249 Series can be manually reversed for opposite-hand operation, but the exact cataloged part number and original door configuration should be matched before installation. Do not assume every installation can simply be reversed without following the Kason procedure.

Polished Chrome Finish

This exact configuration uses a polished chrome finish. Other 1249 variants are available with different finishes, offsets, handed arrangements, non-lift-off options, and non-spring configurations.

That is why the complete manufacturer part number is more useful than simply searching for a “Kason 1249 hinge.”

1249 Series Dimensions

Kason's technical drawing for the 1249 Series shows multiple installation dimensions, including approximately:

• 4-1/2" across the upper hinge body
• 5-21/32" overall vertical reference
• 2-7/8" flange reference
• 2" inner flange reference
• 1-5/8", 2-1/4", and 2-7/16" lower mounting references

Because the hinge has several critical dimensions, do not identify or order it using a single “5-1/2 inch” dimension. Match the manufacturer part number, offset, mounting pattern, handing, and original hinge.

Common Signs of a Worn or Damaged Walk-In Hinge

• Door sags at the latch side
• Door drags on the floor or threshold
• Door does not close squarely
• Latch and strike no longer align
• Gasket compression is uneven
• Spring-assisted closing becomes weak
• Door requires unusual force to close
• Cam movement is rough or binding
• Hinge has excessive play
• Mounting screws repeatedly loosen
• Hinge body or strap is bent
• Condensation or frost appears along one side of the doorway

These symptoms do not automatically prove that the hinge itself is the only failed component. Inspect the other hinges, gasket, latch, strike, mounting surfaces, closer hardware, and door/frame alignment before completing the repair.

Inspect the Other Hinges

Heavy walk-in doors depend on all installed hinges working together. When one hinge is damaged or worn, inspect the remaining door hinges for:

• Cam wear
• Weak spring action
• Loose mounting hardware
• Excessive shaft movement
• Bent straps or flanges
• Corrosion
• Misalignment

Replacing one hinge may not correct door alignment when another hinge or mounting location is also damaged.

Inspect the Door Gasket

Hinge alignment directly affects gasket compression. A sagging door may create gaps even when the gasket itself appears usable.

Inspect for:

• Uneven compression
• Visible air gaps
• Torn gasket material
• Flattened sections
• Frost around the opening
• Condensation near the door perimeter

Inspect the Latch & Strike

A misaligned door can cause the latch to miss or bind against the strike. Before adjusting or replacing latch components, confirm that the hinge system is supporting the door correctly.

Optional Lift-Off Retention

Kason's 1249 documentation shows an optional set screw at the rear of the strap that can be used to prevent door lift-off where required.

Kason also lists a separate non-lift-off version associated with this configuration, so technicians should verify whether the installation requires standard lift-off capability or a dedicated non-lift-off hinge.

Technician Checks Before Ordering

• Manufacturer part number 11249000004
• Kason 1249 Series
• Right-hand catalog configuration
• Flush / 0" offset
• Spring-assisted design
• Cam-rise configuration
• Polished chrome finish
• Original mounting-hole pattern
• Door-to-frame relationship
• Door weight and hinge arrangement
• Condition of remaining hinges
• Gasket compression and door alignment

Do not select a Kason hinge by appearance alone. The 1249 Series includes multiple offsets, handed configurations, finishes, spring options, and lift-off arrangements.

No Verified Public Equipment Model List

Parts Town currently does not publish a model-fitment list for Kason 1249-000004. Fitment should therefore be confirmed through the Kason manufacturer number, original hinge, door construction, offset, handing, mounting pattern, and walk-in equipment documentation.

Commercial Walk-In Applications

Kason 1249 spring-assisted hinges are intended for demanding commercial walk-in refrigeration door applications including:

• Walk-in coolers
• Walk-in freezers
• Restaurant cold storage
• Supermarkets
• Convenience stores

• Hospitals
• Institutional kitchens
• Food distribution facilities
• Commercial foodservice operations

Installation & Service Notes

Walk-in doors can be very heavy. Properly support the door before loosening or removing hinge hardware.

Before removal, document:

• Hinge orientation
• Door handing
• Mounting-hole locations
• Door-to-frame offset
• Shim arrangement where applicable
• Door alignment

Compare the replacement Kason 11249000004 with the original hinge before installation.

After installation, verify:

• Door opens smoothly
• Spring-assisted closing operates correctly
• Cam-rise action is smooth
• Door remains properly aligned
• Door does not drag
• Gasket compression is even
• Latch and strike engage properly
• Mounting hardware remains secure
• 130° hold-open operation functions normally where required

Why Correct Kason Part Identification Matters

Kason 1249 hinges can appear very similar while having different offsets, handed configurations, finishes, spring arrangements, and lift-off features.

Using Kason manufacturer part number 11249000004 identifies this exact catalog configuration as a 1249 Series, right-hand, flush-offset, polished-chrome, spring-assisted cam-rise hinge.
