Those are stick-on slides, it came in a roll 10.5' and was purchased at the Woodcraft store. The angle is1/4"x3", the square tubing is 2-1/2"x2-1/2" 11 ga. If you undertake this project i have one suggestion, unless you have access to a cutting tourch or plasma cutter i would buy the cam lever, cost around $35.00. I made mine from 3/4"x2" flat bar and worked it down with a grinder and files, long process and a pain in the butt.
