Accuride has added carriage bolt holes to several of its heavy-duty slide models, including the 9301, 9307 and 9308. Designed to accommodate applications where a bolt installation is the preferred method, this addition (according to the company) provides for a single-tool installation, which simplifies and speeds mounting, reducing labor time by up to 50%. The square holes accommodate #10 carriage bolt or M-6 fasteners. Holes are located adjacent to existing mounting holes. (562) 903-0200, Accuride.com.
