Sears offers two Gladiator 48" GearTrack Heavy-Duty Channels, model no. GAWC041PZY, for $13.99. (Add two to your cart to see this price.) Opt for in-store pickup to avoid the $8.25 shipping charge. That's tied with our mention from last month and the lowest price we could find by $5. Each channel measures 48x6" and holds up to 75 lbs. per linear foot.
