Overview
Rogue Rig Shims are precision-cut steel plates designed to solve the common problem of uneven gym floors. When installing a rack or rig on a concrete slab with a slope or "high spots," these shims allow for micro-adjustments to ensure your uprights are perfectly plumb and your crossmembers are level. This is a critical step for both the structural integrity of the rig and the safety of the athlete.

Key Features and Specifications
Compatibility: Universal design fits Rogue Monster, Monster Lite, Infinity, and Echo series units.
Material: 11-gauge (1/8" thick) laser-cut steel.
Design: Horseshoe-style "C" shape allows for installation without fully removing the anchor bolts or lifting the upright entirely off the floor.
Dimensions: Sized to match the footprint of standard Rogue rack footplates.
Center Hole/Slot: Features a wide slot to accommodate 3/8", 1/2", and 5/8" anchor bolts.
Finish: Bright Zinc plating for corrosion resistance and long-term durability in garage or commercial environments.
Quantity: Typically sold in packs of 10.
Origin: Made in the USA.
Performance Benefits
Structural Precision: Ensures that pull-up bars and crossmembers are perfectly horizontal, which is essential for consistent bar paths and safe racking of weights.
Vibration Reduction: By eliminating the "gap" between a footplate and an uneven floor, shims prevent the upright from "chattering" or shifting under load.
Easy Retrofitting: The open-ended design means you can simply loosen your floor anchors, slide the necessary number of shims under the footplate, and re-tighten.
Stackable: Multiple 11-gauge shims can be stacked to reach the exact height required to level an upright on a significant slope (e.g., a garage floor designed for water drainage).
Maintenance and Care
Installation Tip: Use a spirit level on the upright and the crossmember simultaneously while adding shims to ensure the entire structure is aligned in all planes.
Hardware Tension: After installing shims, re-torque your Rogue HD Concrete Anchors to ensure a secure connection to the slab.
Corrosion Inspection: While the Bright Zinc finish is highly resistant to rust, periodically check shims in high-moisture environments (like uninsulated garages) to ensure no oxidation is occurring between the shim and the concrete.
Debris Removal: Ensure the area under the footplate is clear of pebbles or dust before sliding the shim in to ensure a perfectly flat contact surface.
Frequently Asked Questions
Q: How many shims can I stack under one upright? A: You can stack multiple shims; however, if you are exceeding 1/2" of total shim height, ensure your anchor bolts are long enough to maintain a safe depth (at least 2"–2.5") into the concrete.
Q: Do these work with wall-mount racks? A: Yes. If the floor is uneven where the uprights of a wall-mount rack meet the ground, these shims are the ideal solution to keep the rack square against the wall.
Q: Will these shims slide out over time? A: No. Once the anchor bolt is tightened, the downward pressure of the rack and the friction of the steel-on-steel connection lock the shim permanently in place.
Q: Can I use these on rubber stall mats? A: These are designed for use between a steel footplate and a hard surface (concrete). If you have mats, it is recommended to bolt the rack through the mats to the concrete, using the shims directly on the concrete if necessary.
