A compact solution to a sprawling problem! This new rack from Rockler herds your F-clamps together and mounts them firmly to the wall or to the Pack Rack (21834 sold separately) so your clamps are where you need them when you need them. Pre-drilled holes are 16" on center for simple mounting to wall studs; slotted holes line up with the Pack Rack. Constructed of sturdy galvanized steel for a lifetime of service. 24-3/8" overall length.
