Snapfix locators are UV stable frost resistant and able to withstand global temperature variations and come with a lifetime guarantee. Snapfix design is unique in the market being manufactured with a ball stud that utilises our EASY CLICK® design which enables easy installation of flat cut letters even when you are slightly out of tolerance on your drilling template. Our medium size has a grooved ridge on the base of the stud to allow for snipping down to required size for unusual shapes that would still require the strength of a medium locator.
