Extended measurement range to ±25 mm supports expansion-joint measurements and larger crack-widths typical of unreinforced masonry (URM) foundations and buildings (URB).Convenient integrated caliper standoffs improve measurement discrimination by a factor of 10 or more when using a quality digital calipers. Calipers are not included and must be purchased separately. Install using thixotropic 5-minute epoxy (Buildera Strupoxy or similar) or #6 sheet-metal screws and plastic anchors.
