Adjustable spacer wedge has moulded plastics triangular frame with screw to adjust width

摘要

The adjustable spacer wedge (1) is made of plastics and forms a triangle with the upper angle arm sufficiently thin that it is flexible. The right angle section (4) has a bolt with a ribbed head knob (5) to allow screwing in or out. The bolt engages the abutment (3) on the underside of the upper arm so that it can be raised or lowered.
