Knipex wall mount

One of my own designs, I'm slowly making a little portfolio. wall mounts for a variety of Knipex tools. Please see the pictures I have these mounted to a Sealey metal tool wall with 4mm screws. I see no reason why you cannot use other screw fixings to secure these to other wall material. The holes for the screws/fixings are 4mm with an 8.5mm section to allow for the screw head. The holes are 25.4mm distance from each other You may have noticed I have two different sets, one set is a generic one for the Knipex grips etc, however I have made another with an extra tab. I noticed that the Knipex tools with the flare in the handles needed to be slightly different, and found that having the tab partway up secures the pliers perfectly.
