Retractable and safety handles have an internal mechanism which requires the handle to be pulled against a spring in order for adjustment to take place, and once adjustment is completed, the handle locks into a rest position. They are suitable for when the handle must be withdrawn during automatic operations. Safety variants can only be operated when manually held in position and will automatically return to the retracted position when released. These handles are plastic, with a steel or stainless steel mechanism.
All handles and knobs supplied by Berger Tools are of excellent quality, and are stocked in the UK.
