Graded slab acrylic case fit guide

Short answer
Standard PSA and CGC slabs fit all three SlabVault sizes (Single, Double and Triple). A standard PSA slab wearing an Original BumperGuard also fits every size, so you don't have to take the bumper off.
The BumperGuard Shield does not fit the Single and is a very tight squeeze in the Double and Triple. We haven't confirmed BGS, SGC or TAG slabs or thick and tallboy holders yet, and we haven't checked other bumper brands one by one. The table below shows each combination.

“Fits” means we sell SlabVault for that combination and have confirmed it. “Not yet confirmed” means we haven’t checked it, not that it fails. If you have one of those, email a photo to [email protected] before ordering.
| Slab | Single | Double | Triple |
|---|---|---|---|
| PSA standard, bare | Fits | Fits | Fits |
| PSA + Original BumperGuard | Fits | Fits | Fits |
| PSA + BumperGuard Shield | Does not fit | Very tight squeeze | Very tight squeeze |
| PSA + another leading brand’s bumper | Should fit; not confirmed by brand | Should fit; not confirmed by brand | Should fit; not confirmed by brand |
| CGC standard, bare | Fits | Fits | Fits |
| CGC + any bumper | Not yet confirmed | Not yet confirmed | Not yet confirmed |
| TAG standard | Not yet confirmed | Not yet confirmed | Not yet confirmed |
| BGS standard | Not yet confirmed | Not yet confirmed | Not yet confirmed |
| SGC standard | Not yet confirmed | Not yet confirmed | Not yet confirmed |
| Thick or tallboy holders (any grader) | Not yet confirmed | Not yet confirmed | Not yet confirmed |
BumperGuard is molded for standard PSA slabs only, so there is no BumperGuard for CGC, BGS, SGC or TAG.
Slab dimensions by grader
Graders rarely publish outer slab sizes. CGC and TAG do; PSA, BGS and SGC don’t on any page we could find. For those, the best public figures are independent caliper measurements, labeled as such below. Check these against your own holders, since sizes shift slightly between holder generations.
| Grader | Official size | Caliper measurement | SlabVault |
|---|---|---|---|
| PSA | Not published | 135.75 × 80.25 × 6.25 mm | Fits all sizes |
| CGC | ≈ 5.30 × 3.15 in (CGC) | 135.00 × 80.25 × 7.50 mm | Fits all sizes |
| TAG | 5.25 × 3.125 in (TAG) | 134.75 × 80.00 × 7.25 mm | Not yet confirmed |
| BGS | Not published | 130.75 × 83.00 × 8.50 mm | Not yet confirmed |
| SGC | Not published | 138.50 × 86.25 × 8.50 mm | Not yet confirmed |
Caliper figures are from PreGradeCards, measured on bare holders (about ±0.25 mm on thickness, ±0.5 mm on height and width). Their figures put the 2024 PSA holder at the same footprint as the older one, about 20% heavier.
SlabVault sizes
- Single (1 slab, $24.99): ½ inch thick, 4 mm clear acrylic panes, 2 lid magnets.

- Triple (3 slabs side by side, $39.99): about 1 inch thick, 8 mm solid acrylic walls, 4 lid magnets.
We don’t publish inner pocket dimensions yet. We’ll add them once we’ve measured every size.
FAQ
Will a PSA slab with a bumper fit in an acrylic case?
In SlabVault, yes: a standard PSA slab wearing an Original BumperGuard fits the Single, Double and Triple. Many other acrylic cases are made for bare slabs only. Phantom Display’s Ultra and Magneto pages, for example, say they hold bare graded cards only and point bumper users to separate GradedGuard and Slabmags versions.
Does SlabVault fit CGC slabs?
Yes. Standard CGC slabs fit all three sizes. We haven’t confirmed CGC slabs wearing a bumper.
Does SlabVault fit BGS, SGC or TAG slabs?
Not yet confirmed. By the caliper figures above, BGS and SGC holders are about 1 mm thicker than CGC, and SGC is also wider and taller than PSA, so don’t assume they fit. Email us a photo before ordering.
Does the BumperGuard Shield fit in SlabVault?
No for the Single, and it’s a very tight squeeze in the Double and Triple. The Shield has its own acrylic panels and is meant to be used on its own. For slabs going into an acrylic case, use the Original BumperGuard.
How big is a PSA slab?
PSA doesn’t publish an outer size that we could find. Independent caliper measurements put a standard PSA holder at about 135.75 × 80.25 × 6.25 mm (5.34 × 3.16 × 0.25 in).
