Sears offers the Gladiator 48" GearTrack Heavy-Duty Channel, model no. GAWC041PZY, for $6.99. Opt for in-store pickup to dodge the $8.25 shipping fee. That's the lowest total price we could find by $4, although we saw it for pennies less last week. Each unit measures 48" x 6" and holds up to 75 lbs. per linear foot.
