The items for sale are the ones in images 1, 2, 3, and 4. The other images are examples of use. The bit holder and socket holder are made to be vertically adjustable and also detachable with a Tajima safety system. It can also be attached to Tajima tool bags, etc. The moving parts of the holder have been adjusted to eliminate unnecessary play, so they don't swing around even when walking. I personally use the same item, and it allows for smooth bit changes without looking, significantly increasing work efficiency, making it an indispensable item. The cosmetic washer parts are made of aluminum or stainless steel, and the bolts and nylon nuts are made of stainless steel. The safety claw part is made of aluminum. *Please note that due to the handmade nature of the product, there may be some minor scratches on the metal fittings during production. We appreciate your understanding. If you have any other requests or questions, please ask in the comments. Tajima Knicks Makita KNICKS Tajima HiKOKI Safety System Tool Pouch Tool Belt Impact Driver
