The Adjustment pin is a handy accessory for a shower setup: it’s designed to be used with the shower grab bars and increases the distance between the adjustment knob and the shower head / shower holder by 35 cm. This extra length makes it easier to position the shower head — especially helpful for people who need more reach or flexibility, for example in accessible bathrooms or for users with limited mobility. The pin thus improves usability and convenience while maintaining a simple, discreet design.
