FAQs
1What equipment is the BD-D81-5 designed for?
The BD-D81-5 is designed for knife switches and heavy-duty operating handles, helping prevent accidental or unauthorized operation during equipment maintenance.
2How do I tell BD‑D81‑5 from other BD‑D81 series locks?
BD‑D81‑5 is specially designed for knife‑switches and large‑duty operating‑handles. The remaining four models are built for rotary knobs, raised push‑buttons, cabinet‑doors and drawer‑transfer‑handles respectively.
3How does the BD-D81-5 differ from other BD-D81 series models?
BD-D81-5 is suitable for knife switches and large operating handles. BD-D81-1 is for rotary knobs, BD-D81-2 for raised push buttons, BD-D81-3 for cabinet doors, and BD-D81-4 for drawer cabinet transfer handles.
4Can the lock cavity be customized for a non-standard knife-switch handle?
Yes. OEM mold customization is available based on your handle drawings, dimensions, or physical samples to provide a properly matched lock cavity.
5Can the device be installed without drilling the cabinet panel?
Yes. A high-strength 3M adhesive installation option is available for suitable thin plastic cabinet panels, helping minimize damage to the mounting surface.
6Will the lockout device move under equipment vibration?
Its reinforced A3 steel base adds stability, while the close-fitting clamping slot helps reduce movement caused by continuous equipment vibration.
