Inquiry (采购产品): C Channel extrusion I was looking for a rectangular channel that is partially open about .5 inch X .5 inch x 24 inch.I'm usiing it as a sliding track so it must be almost closed so that the sliding part doesn't get pulled out . Also, it has to have countersunk screws so I can secure it to a base. Stainless steel or brass would be good. **** Hidden Message ***** Larry Edwards 67037 Company: me E-mail: fightlivefree@yahoo.com **** Hidden Message ***** fightlivefree@yahoo.com
