Litelok X1

The Litelok X1 D-lock has a shackle diameter of 21 x 24mm and it easily fits into our Protector 13mm security chain, as you can see in the image above.

Our larger chains have more internal clearance and so the Litelok X1 will fit every chain in the Pragmasis Protector range from 13mm upwards. It will not fit our Protector 11mm chain.

Litelok X3

The Litelok X3 is a larger lock than the X1. It has a shackle diameter of 24 x 27.5mm which will fit into our Protector 13mm, 16mm, 19mm and 22mm chains.

In the picture above, the Litelok X3 is paired with our Protector 13mm chain.
