This kit comprises a moulded adaptor that attaches to a mounting boss on the rear of DPI 800 series handheld instruments. This also acts as a bench stand-- raising and stabilising the DPI 880 for bench top use. Also included is an adjustable wrist strap and a means of hanging the unit for hands-free operation by way of a snap connector. The adaptor also allows the DPI 800 series handheld instrument to be quickly attached to the belt clip provided. The snap-lock action provides a secure fastening and quick removal.
