Description
Say goodbye to complex multi-part assemblies that fuse or snap. This high-strength, Split into objects and print after arrangement, sliding child lock uses a precision dovetail mechanism that physically traps the sliding bolt without needing bridging or roofs.
Most child locks require perfectly tuned printers to avoid parts fusing together or snapping under load. This slider uses an engineered trapezoidal dovetail profile.
Whether you need a heavy-duty lock for the workshop or a low-profile lock for kitchen cabinets, you can customize every dimension!
