Thicker, stronger aluminum in an innovative shape that provides increased stud rigidity while reducing track wear
Single backer measures 1.250in. wide x .145in. thick aluminum
Double backer measures 1.280in. wide x 2.250in. thick aluminum (1in. hole distance)
Radial lobe shape means the weakest flat corner areas of standard backers are reduced so the corners do not bend like standard backers, plus unnecessary weight is reduced
Combine the best benefits of square and round backers in one design
Available in plain aluminum finish
