  • Description

    AVONGARD - TP11 Plus Tell-tale 

    Avongard Plus Tell-Tales can be used to monitor horizontal or vertical movement across a crack on a flat surface. The Plus offers two upgrades to the standard design. Rather than presetting the two measuring plates together at zero with tape, the plus uses four small pegs, which ensure alignment during installation and then removed during monitoring. The plus also provides measuring flats, which allow accurate readings to be taken with calipers during monitoring. 

    • Fix using Screws AF11 and Adhesive AE14 (not included).
    • Supplied with full instructions and Crack Record Sheet.
    • Weather-resistant.
    • Caliper sold separated.
