Blue 25mm steel shackle safety lockout padlock
BD-G53
The BD-G53 blue safety lock features a 6mm anti-side-pressure steel lock beam paired with an ABS engineering plastic lock body and a highly visible blue marking for easy on-site identification of the compressed air system’s isolation status.
- Blue markings—used to indicate the isolation status of commands and compressed air, allowing for quick identification by on-site personnel.
- 6mm anti-side-pressure steel lock beam—prevents false locking and avoids potential hazards caused by misoperation.
- ABS engineering plastic lock body—passes temperature resistance testing from -20°C to +177°C, UV resistant, and impact resistant.
- Key-retrieval lock cylinder—prevents keys from being lost on-site and ensures the padlock is not left behind.
- Custom Labels — Waterproof and stain-resistant PVC bilingual (Chinese and English) labels, rewritable.
- Four-Level Key System — KD/KA/KDMK/KAMK optional, supports grouping and multi-level management.
- Unified Laser Encoding — Lock body and key are uniformly laser-coded, with the markings archived.
- Write-on PVC Label — Waterproof, stain-resistant, corrosion-resistant, supports multiple languages and logo customization.
