REP Fitness SR-4000 Squat Rack Specs: Height, Footprint and Hole Spacing

The REP Fitness SR-4000 Squat Rack is a squat stand in the $700 to $800 price band. It is a two post stand with a long flat foot base, which is REP's answer to wanting 3 by 3 inch steel without drilling a slab, and the base is the reason its published depth is over 70 inches.

What are the REP Fitness SR-4000 Squat Rack specifications?

Every figure below is the manufacturer's or retailer's published specification. Where a figure could not be verified against a published source it is omitted from the table rather than estimated, because a guessed dimension is worse than a missing one on a page you are using to decide whether something fits.

What ceiling height does the REP Fitness SR-4000 Squat Rack need?

Clear ceiling height is the distance from the finished floor to the lowest obstruction over the rack footprint, which in a basement is a duct run, a beam, a sprinkler head or a light fixture far more often than it is the ceiling itself. The rule is the rack height plus about 2 inches.

For this rack that is 98 inches, derived from the published 96 in height. That figure is our arithmetic on the manufacturer's number, not a manufacturer's number itself.

This rack does not clear a 7 foot basement, and no amount of careful assembly changes that. If your room is in that band, look at a squat stand in the 70 to 74 inch range instead, which is a different piece of equipment rather than a compromised version of this one. Run your own measurement through the ceiling height calculator before ordering, and see the rack height and clearance chart for how the bands compare.

There is a second clearance almost nobody plans for: you have to stand the frame up during assembly. Tilting a 96 inch structure into place in a 98 inch room does not work, and a heavy gauge frame is far harder to raise than a light one. If your headroom is within about 2 inches of the rack height, build it lying down and raise it with a second person.

How much floor space does the REP Fitness SR-4000 Squat Rack need?

The barbell sets the floor space, not the rack. A 7 foot Olympic bar is 86.6 inches long, so any barbell lift needs at least 108 inches, which is 9 feet, of clear width no matter how compact the frame is. That is true of every rack on this site and it is the reason a very narrow rack rarely solves a narrow room.

The published footprint here is 52.4 by 71.4 inches, about 26 square feet of floor. Add roughly 24 inches of walk-around on the two sides you load plates from and the practical zone is closer to 8.4 by 8 feet, which is derived rather than published. The gym space planner will fit it against your actual room dimensions.

What attachments fit the REP Fitness SR-4000 Squat Rack?

Three numbers decide attachment compatibility: the upright tube size, the hole diameter and the hole spacing. An attachment made for 2 by 3 inch uprights on 5/8 inch hardware will not fit 3 by 3 inch uprights on 1 inch hardware, and spotter arms that almost fit are spotter arms that do not fit.

This rack uses 3 x 3 in 11 ga uprights on 5/8 in hardware, with 2 in with 1 in westside spacing in the bench zone hole spacing. Same 3 by 3 inch, 5/8 inch pattern as the PR-4000, so the 4000 series accessory catalogue transfers directly. Compatibility across brands is a convention rather than a guarantee. Manufacturers revise dimensions between production runs without renaming a model, so the only safe check is to measure your own uprights: outside tube dimensions, hole diameter, and hole centre to centre spacing. The hole spacing and gauge chart covers what each measurement means.

At 11 ga the upright wall is about 0.12 inches thick. Gauge is a wall thickness designation rather than a strength rating, and a lower gauge number means thicker steel: 11 gauge is roughly 0.120 in, 12 gauge roughly 0.105 in, and 14 gauge roughly 0.075 in. Thicker wall resists the flex you feel when a heavy bar is racked off centre, which is a different thing from the rack's published capacity.

The one accessory worth buying with any rack used alone is a set of spotter arms , and the compatibility check above is exactly why: confirm the tube size and whether the holes are 5/8 inch or 1 inch before ordering. Where anchoring is called for, half inch wedge anchors are the common slab specification.

What should you know before buying the REP Fitness SR-4000 Squat Rack?

• Sold at 96 in or 103 in. Both need well over 8 ft of clear ceiling, which rules out most basements before any other consideration.
• The 71.4 in depth is the long flat foot base. REP states that base is what removes the need to bolt the rack down, so shortening it is not an option.
• Base side holes are 1 in while the upright holes are 5/8 in. Check which one an accessory needs.

How does the REP Fitness SR-4000 Squat Rack compare with similar racks?

Compared here against other squat stands in our data, on the four figures that actually decide a purchase: how tall it is, what the uprights are, how the holes are spaced, and what the manufacturer rates it to. A blank cell means we could not verify that figure, not that the rack lacks the feature.

Who is the REP Fitness SR-4000 Squat Rack for?

A tall garage where you want 3 by 3 in steel and cannot or will not anchor it.

A stand rather than a cage, so the honest limitation is what you can bail out of. There are no four post safeties to dump a failed squat backward into, and benching alone under a stand means fitting spotter arms and trusting them. In exchange you get a genuinely mobile 1,000 lb rated frame in the same accessory family as the PR-4000. At 96 in tall it is a garage rack, not a basement one.
