A clean, functional door handle bumper that presses onto round door handles and absorbs impact before the handle hits the wall. No adhesives, screws, or tools required.
The inner diameter is 0.2mm undersize for a snug press fit. If your handle is between sizes, go one size up or use XY compensation.
Available sizes (inner diameter → handle OD):
9.8mm → 10mm handle
15.8mm → 16mm handle
18.8mm → 19mm handle
19.8mm → 20mm handle
21.8mm → 22mm handle
24.8mm → 25mm handle
29.8mm → 30mm handle
31.8mm → 32mm handle
