This custom 304 stainless steel rotating compression door handle latch combines a long lever, square-drive spindle, and mating keeper to pull a door securely against its seal. The over-center compression action is suited to heavy or frequently operated doors where consistent gasket pressure and straightforward manual operation are required. Left- and right-hand versions can be supplied to match the opening direction and installation layout.

Design and Ordering Considerations
Compression performance depends on door thickness, gasket compression, keeper position, spindle length, frame geometry, and opening direction. Please provide the door and frame drawing, required left- or right-hand operation, panel thickness, seal compression target, mounting-hole pattern, and available installation clearance.
The reference dimensions shown in the supplied specification images describe one configuration only. They should not be used to drill a production door or frame until the project drawing and physical interface have been approved.

Quality Control and Inspection
Inspection can include material verification, casting and machining review, spindle fit checks, lever rotation testing, keeper engagement inspection, mounting-pattern measurement, surface-finish inspection, and trial assembly. Critical interfaces are checked against the approved drawing. Learn more about AODSON quality control and assurance.
OEM Customization and RFQ Requirements
For an accurate quotation, provide the door type, panel thickness, left- or right-hand requirement, handle quantity, spindle profile and length, keeper reach, mounting-hole layout, compression travel, finish, and operating environment. Where possible, include a section drawing of the door, seal, and frame. Browse related building hardware or request a quote for a custom configuration.
Frequently Asked Questions
Can you supply both left-hand and right-hand handles?
Yes. Left- and right-hand versions are available. The opening direction and viewing side should be marked clearly on the RFQ drawing to avoid handing errors.
Can the spindle and keeper be adjusted for different door thicknesses?
Yes. Spindle length and keeper reach can be reviewed for the door and seal stack-up. Final dimensions are confirmed on the approved drawing.
Are the 142 mm length and 90° rotation fixed?
They describe the reference version shown. Alternative lever lengths, mounting layouts, and operating geometry may be available subject to load and manufacturability review.
