This pocket tape measure from SHINWA with a 25 mm wide tape is designed for regular outside use under harsh conditions. The carbon steel tape is nylon-coated to protect it against moisture. The highly effective return spring is made of carbon steel. The belt clip is separate and firmly attached to your belt, you snap the tape into this clip. It is released from the clip by pressing the top red button. Even in the most awkward position the tape will not part company with the belt clip as would be the case with more basic belt clips. A spring-loaded retaining cord with a wire core extendable up to one metre and with a snap hook at each end makes it virtually impossible to lose this tape even if you detach it from your belt - or if it happens to drop out of your hand.
