Olympus Disc Tumbler Cam Lock For Cabinets
Olympus disc tumbler cam lock is a cam lock from Olympus Lock, Inc. that uses a disc tumbler mechanism to secure drawers and doors, giving casework builders a compact lock solution for common furniture and cabinet layouts. The lock has a 2 inch cylinder that is keyed alike 390, so multiple locks keyed to 390 can be operated with the same key where a shared keying plan is needed. The lock is described as having a maximum cylinder length of 1-13/16, which ties directly to allowable material thickness at the front of the cabinet or drawer. The matte black 961-US19-C390A finish presents a uniform dark appearance on visible faces, matching hardware that uses a similar black tone across a project. As a cam lock in the cam locks product class, it ties into standard cam-based locking layouts that many installers already use.
Cam Lock Details That Support Daily Use
- The lock comes assembled, so the cylinder and body arrive already together, saving bench time normally spent building up lock components before installation into casework.
- The lock passed the ANSI/BHMA Grade 2 cycle test of 20,000 cycles, including key insertion and removal, so it is tested for repeated locking and unlocking in regular cabinet service.
- The cylinder and body are assembled via a patented retainer staple, which holds these parts together during handling and installation, supporting consistent alignment of the keyway and cam.
- The design uses a revolutionary cylinder plus cylinder extender that allows cylinders to be swapped between different size cam lock bodies, giving shops flexibility when matching lock bodies to different panel thicknesses while keeping keying consistent.
- Custom keying typically ships direct from the manufacturer in 48-72 hours, so projects requiring specific key codes can be supported without long waits in the project schedule.
Installation Fit For Overlay And Flush Layouts
The cam lock is specified for drawers and for right-hand or left-hand doors, so the same lock model can be used across different swing directions and sliding fronts in a run of cabinets. It supports lipped or overlay construction using a 1-1/2 inch straight cam, and it also supports flush construction using a 1-1/8 inch extension cam with 11/32 inch offset, letting installers match the cam geometry to how the door or drawer front sits relative to the cabinet frame. For overlay applications, the combined thickness of the front and frame cannot exceed the cylinder length listed, tying cylinder selection directly to actual build-up of materials at the opening. This constraint helps keep the cam within its operating range so it can rotate and engage the strike or frame as intended once mounted.
Where This Olympus Cam Lock Excels In Use
Using The Cam Lock On Drawers And Doors
The lock is specified for drawers along with right-hand and left-hand doors, so a single part number can serve mixed storage types in a project, reducing the variety of locks that need to be stocked. For lipped or overlay construction, the 1-1/2 inch straight cam reaches behind the overhanging front, letting the cam catch a frame or strike when the key is turned. For flush construction, the 1-1/8 inch extension cam with 11/32 inch offset positions the cam correctly relative to the door or drawer front, helping align the cam with the frame line in flat-front casework. The 90 degree cam turn means the cam moves from locked to unlocked within a quarter-turn rotation, providing a clear stop position that feels predictable when operating the key. Because the key is removable in both locked and unlocked positions, users can leave the key out when the cabinet is open or closed, which can support key control preferences in shared work areas.
Details That Help Maintain Alignment Over Time
The cam lock uses a spur washer with an eyelet, and when this spur washer is screwed into place it prevents lock rotation and keeps the fixing nut from loosening after installation, helping maintain cylinder orientation in the panel. By holding the body against rotation, the spur washer supports consistent keyway alignment so the key enters cleanly over time. The cylinder and body assembly via a patented retainer staple keeps these components fixed together as one unit, reducing the risk of parts separating when the lock is handled or inserted through the mounting hole. The revolutionary cylinder plus cylinder extender design allows a given keyed cylinder to be moved between different size cam lock bodies, so shops can adapt to varying door or drawer thickness while preserving a chosen keying system. Since the lock passed the ANSI/BHMA Grade 2 cycle test of 20,000 cycles that includes key insertion and removal, its operation has been exercised under repeated use conditions, supporting projects where locks see frequent daily operation in cabinets and casework.
Common Questions About Olympus Cylinder 961-US19-C390A
What type of applications is this cam lock intended for?
The Olympus disc tumbler cam lock is stated for drawers and for right-hand or left-hand doors, so it is intended for typical cabinet and casework fronts using cam-based locking.
How does the keyed alike 390 cylinder help on a project?
The 2 inch cylinder is keyed alike 390, so multiple locks with the same 390 keying can be operated by one key, simplifying key control across several cabinets.
What does the ANSI BHMA Grade 2 cycle test mean in practice?
The lock passed the ANSI/BHMA Grade 2 cycle test at 20,000 cycles with key insertion and removal, indicating it has been exercised for repeated cabinet locking and unlocking operations.
How does the spur washer help keep the lock stable?
The lock uses a spur washer with an eyelet that, when screwed into place, prevents the lock from rotating and keeps the fixing nut from loosening, helping maintain orientation in the panel.
What is the benefit of the cylinder and cylinder extender design?
The lock uses a revolutionary cylinder plus cylinder extender that allows cylinders to be swapped between different size cam lock bodies, supporting flexible matching to various material thicknesses while holding keying choices.
How far does the cam turn between locked and unlocked positions?
The Olympus cam lock provides a 90 degree cam turn, so the cam moves from locked to unlocked with a quarter-turn rotation of the key, giving clear end positions during operation.
