Interchangeable Locking Devices

Automatic Beam Locking Devices

Interchangeable pallet racking with teardrop shaped holes from UNARCO offers a variety of locking devices. Interchangeable pallet racking is the industry standard. Adding onto your existing interchangeable pallet racking from any manufacturer is easy; the patented Interchangeable Push Lock and Gravity Lock connections are easy to install and cannot be “sprung.” The Push Lock automatic plunger style locking device will work with any interchangeable rack.

Gravity Lock – Interchangeable Beam Locking Device

Relocating beams is a snap and requires no tools. The interchangeable locking pin is raised as the pallet rack beam is inserted and then will rest in place once the beam seats. The beam is locked and held in place by the force of gravity, even as forklifts or pallet loads below cause uplift. The locking mechanism is built into the interchangeable beam connector so it cannot be lost or misplaced.

The Gravity Lock is one of the few integrated locking mechanisms that can withstand the zinc coating, galvanizing bath. Since it is integrated into the beam connector, there are no outside operations or areas that are not zinc coated. This solution is the most environmentally friendly connection for outdoor garden centers and freezer and cold storage pallet rack applications.


Push Lock – Interchangeable Plunger Style Automatic Beam Locking Device

UNARCO offers a spring-loaded automatic locking device with tapered studs to fit every manufacturers’ interchangeable pallet racking. The UNARCO Push Lock will work with odd-shaped teardrop holes and tapered interchangeable pallet racking.

When the beam is inserted into the teardrop holes in the frame, the plunger locking mechanism "clicks" to let you know that your pallet rack beam is securely installed.

System Highlights:

Pallet Rack Beam Connectors are available in bolted and automatic locking style designs.

  • Gravity Lock integrated connector

  • Push Lock plunger style automatic lock

  • Connectors with 2 - 6 studs available

  • All interchangeable beam connectors allow through-bolts for down-aisle support

  • Cold-headed steel studs keep beams engaged in the rack

Teardrop and bolted rack connectors are available in multiple heights and configurations. Beams can be mounted on the connectors to be flush with the floor for lower levels or flush with the top of the connector leaving a gap at the bottom beneath. Special connectors can be designed to meet stricter design codes or high seismic areas.

Beam Connectors Up to 12" Tall

Both the Gravity Lock and Push Lock connectors have heavy-duty studs that are specially designed to lock into teardrop keyholes.

UNARCO offers different size beam connectors to meet your rack capacity and seismic requirements. All are engineered to prevent accidental disengagement and keep beams locked in place, even in the most active warehouse.
