Mortise Deadbolt Cylinders with Cloverleaf Cams for Multi-Point Shootbolt Cases
Engineering Overview: Engineering guide on cloverleaf and multi-lobed drive cams on threaded mortise cylinders for high-security commercial multi-point lockcases.
Technical & Engineering Specifications
| Material | Heat-Treated High-Carbon Sintered Steel |
|---|---|
| Cam Format | Cloverleaf / Multi-Lobed Screw-On Cam |
| Application | Commercial Multi-Point Entrance Deadbolts |
| Cylinder Thread | 1-5/32"-32 UNS Standard Mortise |
Multi-Lobed Drive Geometry
Standard straight cams cannot properly engage multi-point shootbolt linkages. High-security commercial mortise lockcases specify Cloverleaf (Adams Rite / Multi-Lobed) Cams.
Kinematic Load Transfer
- Triple-Lobed Profile: The cloverleaf shape maintains continuous contact with the internal deadbolt slide throughout a 360° rotation.
- Heavy Shootbolt Operation: Generates the high linear force needed to drive top, middle, and bottom locking bolts into structural frames simultaneously.
Frequently Asked Engineering & Selection Questions
Q1: What is a cloverleaf cam used for?
It provides continuous driving contact to smoothly operate heavy multi-point locking shootbolts inside commercial mortise doors.
