At Lowe's, buy one Gladiator 48" GearTrack Heavy-Duty Channel
, model no. GAWC041PZY, for $10.98
and get a second one
. (The second one is automatically added in-cart.) Choose in-store pickup
to avoid the $5.99 shipping charge. That's $5.49 per unit, $2 under last month's mention of a pair of GearTrack channels shipped, and the lowest price we could find for this quantity with pickup elsewhere by $11. Each unit holds up to 75 lbs. per linear foot.
