Pallet Rack Accessories

Row spacers set the flue space, the open gap between the loads of back-to-back rows. J pins provide a secondary lock at each beam connection. Card and label holders identify each storage position.

North Carolina, South Carolina, Georgia, and Virginia make up our main service area. In 2025 we also completed projects in 24 other states.

A row spacer connects the rear uprights of two rows that stand back to back. It holds the rows a fixed distance apart, keeps the aisles on both sides straight, and makes the rack more rigid.

The 12-inch spacer is the most common size. It allows a 3-inch pallet overhang past the rear beam of each row and still leaves 6 inches of open space between the loads. That open space is the flue space.

J pins and beam locks secure the connection between each beam and its upright. A beam end hooks into slots in the upright and has a built-in lock. A J pin is a secondary lock. It drops through aligned 3/8-inch holes in the beam connector and the upright and keeps the beam seated if the built-in lock is lost or damaged. J pins are also called drop pins, safety clips, beam clips, or gravity pins.

A rack inspection checks every beam connection for the conditions below, including damaged or missing pins and locks.
