“ProStack helps our operators setup quicker, easier & safer.”

A Better Cribbing Solution
Interlocking Design
By interlocking together, ProStack® Plastic Cribbing Blocks create a significantly safer equipment set-up under the stabilizer or outrigger foot. This increases safety in situations where the ground is not level. The more load you exert on this outrigger construction cribbing block set-up, the tighter it locks together and better it performs.
The Engineered Difference
Because ProStack Cribbing is made from an engineered material, the performance of ProStack Plastic Cribbing Blocks is predictable and reliable unlike most other solutions commonly deployed in the field. The engineered cribbing material is strong, impervious to environmental conditions, and all components are ergonomically designed to be user-friendly.
Strength and Performance
ProStack® Plastic Cribbing Blocks provide height for operators in environments where changes in grade require cribbing to assist in leveling the equipment. ProStack construction cribbing blocks are designed for equipment with outrigger loads that do not exceed 110,000 pounds, such as boom trucks, digger derricks, and aerial devices.
Easy Setup and Breakdown
The entire cribbing block system can be set in place or stored in minutes. Individual, lightweight cribbing wedges, blocks, and more parts with handles designed for simple lifting and carrying make this a winning solution for crews.
STEP 1
The base SafetyTech Outrigger Pad is positioned first.
STEP 2
Add the first layer of (2) ProStack Cribbing Blocks.
STEP 3
Add the second layer of (2) ProStack Cribbing Blocks crosswise to the first.
STEP 4
Place the ProStack Grip Pad on top of the stack.

FAQs
Q. What size cribbing blocks do I need?
Heavy Duty ProStack Cribbing Blocks are designed for equipment with outrigger floats that do not exceed 24” x 24” and outrigger loads that do not exceed 110,000 pounds. Medium Duty ProStack Cribbing Blocks are designed for equipment with outrigger floats that do not exceed 12”x12” and outrigger loads that do not exceed 55,000 lbs. ProStack cribbing blocks can be used for industrial applications as well. Contact us to determine if Medium or Heavy Duty is the right choice for your equipment.
Q. How does the durability of your interlocking plastic cribbing blocks compare to wood?
ProStack Plastic Cribbing Blocks are constructed of recycled engineered thermoplastic materials. Because of their reliable molecular, strength and stiffness properties they deliver quantifiable and consist results. ProStack cribbing is virtually impervious to absorption, and they are guaranteed against splintering, cracking and breaking. Wood is a natural material that begins to decay the moment it is cut. Because wood is wood is porous and is subject to the environment, including insects and dry rot wood fibers will splinter crack and break and can have large variations of strength, stiffness, and reliability under pressure.
Q. Can I set my outrigger foot directly onto the cribbing stack?
Yes, but it is not advised specifically when supporting operating equipment. As a best practice use the ProStack Grip Pad as your top layer of the cribbing stack. It protects the interlocking surface of the blocks and safely provides grip for your outrigger foot.
Q. Do the blocks interlock with the pad?
Yes, the base outrigger pad has a matching interlocking pattern manufactured into the surface.
Q. Can our company name be added to your cribbing blocks?
Not at this time. However, we can engrave a company name or logo on the surface of the base SafetyTech Outrigger Pad.
Q. Do you offer custom cribbing block sizes, shapes, and thicknesses?
Not at this time. If you have a specific need, please contact us and we would be happy to see what other solutions may be better suited to your needs.
Q. Are your plastic cribbing blocks resistant to water and chemicals?
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.
Q. Are Pyramid Lock Cribbing blocks flammable?
Slot Lock Cribbing blocks are flammable, but not combustible. Avoid using near open flames.
Q. I already have DICA outrigger pads, can I use them with ProStack cribbing blocks?
Yes, we would recommend placing a 24”x24” ProStack grip pad between the top of your current pad and the bottom of the ProStack cribbing blocks. That will provide full contact between the cribbing and SafetyTech Outrigger Pad as well as protecting the Pyramids and improving friction between the two different products. The size of the pad is important. For Medium duty blocks, the pad needs to be at least 24’x24” and 2 “ thick. For Heavy Duty cribbing blocks, the outrigger pad size needs to be at least 36” and 2″ thick.
Testimonials
Having ProStack plastic cribbing blocks on our concrete pumps gives our operators the ability to set up quicker, easier, and above all else, safer! The entire ProStack cribbing block system has given us a competitive edge in the market by allowing us to safely set up our equipment at minimal inconvenience to the general contractor. – Scott Sutherland, AJ’s Concrete Pumping.
I recently purchased these blocks for my new truck and love these things! – Matt Swearingen, Matt’s Tree Service
