STEP 2

Position the first layer of cribbing blocks onto the outrigger pad so that they lock into place.

STEP 3

Cross-stack additional layers of Slot Lock Cribbing Blocks to achieve your desired height.

FLAT BOTTOM SETUP

Flat Bottom ProStack Slot Lock Cribbing Blocks with an interlocking flange on the top side.

STEP 1

FLAT BOTTOM blocks are to be used as a base layer with the flat bottom FACING DOWN. They can also be used as a top layer with the flat bottom FACING UP. All blocks in a stack must be oriented so that the large flat “working surfaces” are in FULL CONTACT with the layer above and below.

STEP 2

Positon the second layer of cribbing blocks onto the first layer so that they lock into place.

STEP 3

You can add an optional Neoprene grip pad to increase friction between ProStack Cribbing Blocks and stabilzer/outrigger foot to help prevent sliding.

Yes, TuffGrip Handles can be installed on your Slot Lock Cribbing Blocks. If you already have Slot Lock Blocks, TuffGrip Handles can be shipped to you for field installation.

Yes, the outrigger pad is fully capable of being used without the cribbing blocks.

ProStack Plastic Cribbing Blocks are constructed of post-consumer and post-industrial recycled materials and additives that are virtually impervious to absorption, and are guaranteed against splintering, cracking and breaking. The predictable molecular nature of ProStack material provides excellent strength, stiffness and reliability under pressure. Wood on the other hand is a natural material that begins to decay easily. As such, it’s continually subject to moisture, insects and dry rot which results in large variations of strength, stiffness, and reliability under pressure.

Yes, SafetyTech Slot Lock base outrigger pads have slots manufactured into the surface that allow the ProStack Slot Lock Blocks to lock into place.

Yes, the cribbing blocks are impervious to water and resistant to chemicals commonly found on construction sites, parking areas and roads. Please contact us at 800-610-3422 with any specific use or environment concerns.

Slot Lock Cribbing blocks are flammable, but not combustible. Avoid using near open flames.

Yes, they are impervious to water and resistant to chemicals commonly found on construction sites, parking areas and roads. Please contact us if you are concerned about a particular chemical.

Slot Lock Cribbing Blocks can be used on a non-slotted outrigger pad with the following considerations:

  • The rated capacity of the blocks is not exceeded.
  • There are not any voids under the bottom blocks.
  • The blocks are level.
