Adjustment Pad Instructions
Every Nightfall Aluminum Slab Protector ships with adjustment pads already installed for a secure fit on standard PSA slabs.
Additional adjustment pads are included in the box and can be added to improve the fit for standard CGC slabs. Because the measured CGC slab is approximately 0.0625 inch narrower than the measured PSA slab, a CGC slab may have more side to side movement without the extra pads.
- Standard PSA slabs should use the preinstalled pad configuration.
- Standard CGC slabs may need the additional included pads for a snugger fit.
- Pad placement can be adjusted to match your slab.
- Slight movement may remain with some CGC slabs even with the extra pads installed.
- Do not force a slab into the protector. If it does not fit, contact us before continuing.

- Measure your slab's height, width, and thickness.
- Compare your measurements with the tested slabs in this guide.
- Contact Ironfang TCG before purchasing if your slab is unusual or its dimensions differ significantly from the tested slabs above.
