Verified Product Specifications

Function and Commercial Applications

This closer helps return a compatible heavy hinged door toward its closed position. The arm travels through the roller guide as the door moves. Door weight, hinge action, mounting strength and available clearance must all be evaluated when selecting the assembly.

Suitable applications include commercial walk-in cooler and freezer doors that meet the manufacturer's installation requirements. A refrigerator brand, collection assignment or similar-looking arm does not establish fitment.

Common Symptoms to Investigate

• The door no longer returns reliably after opening.
• The arm binds or loses proper contact with the guide.
• The closer or guide moves at its mounting points.
• Closing force changes unexpectedly.
• The spring mechanism, arm or mounting hardware shows damage.

Inspect hinges, door alignment, gasket interference and mounting security before replacing the closer. Additional spring tension should not be used to compensate for an unresolved mechanical obstruction.

Before You Order

• Match manufacturer number 11097000004 to the original closer or equipment documentation.
• Confirm the door weight and required closing force.
• Measure door offset and compare mounting locations with the manufacturer drawing.
• Identify door handing and whether the hinges raise the door during opening.
• Check clearance throughout the complete door swing.
• Confirm the assembly components and fasteners supplied with your order.

Installation and Service Notes

This is a high-tension device. Installation and adjustment should be performed by a qualified technician following the Kason instructions. Secure the closer to a structural jamb member as low as practical, and position the guide to maintain arm contact throughout door travel.

Kason limits winding to 14 notches. Do not stand between the arm and door during adjustment, and never use the winding pawl to hold the door open. Follow the manufacturer's locking-pin procedure and verify operation after installation.

Frequently Asked Questions

Is this a hydraulic door closer?

No. The 1097 uses spring action. Match the mechanism and mounting arrangement specified for the original installation before replacing another closer type.

Is this intended for a lightweight door?

No. Kason recommends this high-tension series for doors exceeding 200 lb. Confirm the application before purchasing; greater closing force is not automatically better for every door.

Can it be installed on a left-hand door?

Yes. Kason documents an inverted installation on the lower left-hand jamb. Follow the manufacturer's drawing for the correct orientation.

Can it accommodate an offset greater than 1-5/8 inches?

That requires manufacturer guidance concerning shimming or other installation considerations. Do not assume the standard arrangement will fit a larger offset.

Is 18 inches a verified overall arm measurement?

This listing does not specify an exact overall arm length. Use the manufacturer drawing and your existing mounting measurements to evaluate fit.

Will increasing spring tension fix a door that binds?

Inspect the source of the resistance first. Hinge wear, misalignment, gasket interference and damaged mounting points require correction rather than additional closing force.

What should I provide for identification help?

Provide the closer markings, door weight, offset, hinge type and photographs of the complete installation. Call 631-873-0509 for help comparing the replacement before ordering.
