'One-for-all' safe isolation
30 April 2015
The LOK6 from Martindale Electric is a universal locking off device for fuse carriers. Designed to restrict finger access to live contacts and prevent the reinsertion of a fuse whilst maintenance is in progress, it is suitable for Red Spot and other similar style fuse holders.

It's easily adjustable to fit fuse holders from 20 to 100A, providing a 'one size fits all solution'. It is said to improve safety and save time sourcing the right device for the job.
The new LOK6 uses an effective clamp system to grip the wall of the Red Spot style fuse holder base, eliminating the possibility of damage.
Designed to provide the user with maximum protection, LOK6 is clamped adjacent to the terminal at one end of the fuse holder, rendering it safe against accidental finger access. As an additional safety measure, it includes an integral sliding cover which can be adjusted to restrict accidental finger access at the far end of the fuse holder base.
Manufactured without any metal parts, the LOK6 is constructed from a resilient flame-retardant blend of Polycarbonate and ABS for high impact strength and long term durability.
Designed in Martindale's distinctive yellow casing, the new locking off device is quick to install without the need for any tools.
THE LOK6 is suitable for use with a wide range of locking padlocks with wire shackles to 7mm wire diameter. For added safety, Martindale Electric recommends using the insulated padlock PAD20R.
Also Available from Martindale Electric is a full range of locking off kits and accessories, including proving units and voltage indicators suitable for use in all installation categories up to 1000V CAT IV.
