Chisel holder - SS system

One of many wall hanging tool holders. This one is designed to hold a selection of chisels. At the top the hole diameter is 18.5mm and at the bottom 13.0mm. Max clearance to insert chisel is 15mm at the top, 13mm at the bottom. My chisels are just cheap VonHaus ones.All wall hanging tool holders come with countersunk holes for screws to attach to a wall and are designed to interlock with other holders in my collection (always adding new ones).
