Trapezoids are a great way to mark a helmet. Each Trapezoid is cut from 3M Scotchlite Reflective Vinyl. They are sold as a set of 5 so that markings can indicate rank, service, company colors or fire apparatus. Trapezoids measure 2-1/8 x 1-7/8 each.
Theyre tets... if your buying them. You know what theyre for and why you need them. Theyre reflective and sticky... they replaced my red ones since the dept. i work for required our tets to be yellow as they came from the manufacturer... they did the trick at making my QM happy...
