Martindale LOK6 Universal Fuse Carrier Isolation Lock

The Martindale LOK6 Universal Fuse Carrier Isolation Lock is designed to enhance safety during maintenance by preventing reinsertion of fuses and limiting finger access to live contacts. Its adjustable design fits a wide range of Red Spot and similar fuse holders, covering 20A to 100A, making it a versatile solution for electrical isolation.

Durable and Safe Construction

Manufactured from a flame-retardant polycarbonate and ABS blend, the Martindale LOK6 offers high impact strength and long-lasting durability. Its bright yellow casing ensures easy identification in busy environments, promoting safe working practices. The absence of metal parts reduces the risk in live working conditions.

Versatile and Easy to Use

The Martindale LOK6 works with locks featuring loops up to 7mm wide. Martindale suggests using the PAD11RD or covered PAD21RD locks for secure fastening (sold alone). Its flat design lets most cabinet doors shut after setup, offering ease without reducing safety.

Setup is quick and tool-free, saving time and effort on-site. With its universal fit and strong build, the Martindale LOK6 provides dependable lockout performance, helping ensure safer maintenance work.
