Product Description

Specify BUILDERA CRACKPOINT™ TR50ti Caliper Marks for all indoor, outdoor, and corrosive environments where high reliability and vandal resistance are desirable.

BUILDERA manufactures the BUILDERA CRACKPOINT™ TR50ti from commercially-pure titanium to aid measurements of structural cracks to within ± 0.001” (± 0.025mm) typical resolution. The exclusive caliper- groove design confidently interlocks with user-supplied analog or digital calipers to improve measurement accuracy and consistency. Ideal for saltwater and harsh industrial outdoor use, all-titanium construction offers superior corrosion resistance—even when compared to type 316L stainless steel.

Mount with tamper-resistant stainless steel screws (supplied) and optional structural adhesive. Available in single-groove (TR50ti-A) and dual-groove (TR50ti-B) versions. Starter kit includes (1) TR50ti-A, (1) TR50ti-B, (2) anchors and (2) security fasteners.
