Westside hole spacing means a power rack’s uprights have holes spaced 1 inch apart through the bench-press zone, instead of the usual 2 inches — so you can set your J-hooks and safeties in finer increments and land the bar exactly where you want it.It’s a small spec with a real daily payoff for anyone who benches in their rack, and a non-issue for anyone who doesn’t. Here’s what it actually changes.
The problem tighter spacing solves
A rack’s uprights are drilled with a row of holes, and your J-hooks and safeties pin into whichever pair you choose. With standard 2-inch spacing, your only height options are two inches apart — which is fine for a squat, where an inch either way barely matters. But for the bench press, it’s often not enough resolution: the perfect J-hook height for a smooth unrack, or the perfect safety height just below your chest touch, frequently falls betweentwo holes. You end up settling for “a bit too high” or “a bit too low.”
1-inch (Westside) spacing halves that increment in the bench zone, so you can put the J-hooks and the safeties exactly where your setup wants them. On a bench, where a single inch changes whether you can unrack cleanly or whether the safeties catch at the right point, that precision is genuinely useful.
Why it’s mostly in the bench zone
On most racks that advertise it, the 1-inch spacing runs only through the lower-to-mid section — the bench zone — and the upper section stays at 2-inch spacing. That’s deliberate: fine adjustment matters most where you bench and set safeties for pressing, and matters least higher up where you just need J-hooks at squat height. Concentrating the tight spacing where it’s useful keeps the rack simpler and cheaper to make without giving up the benefit.
Where the name comes from
The term is borrowed from Westside Barbell, the well-known powerlifting gym associated with Louie Simmons, whose setups popularized the tighter bench-zone spacing. “Westside spacing” became industry shorthand for a 1-inch hole pattern in the bench area, and today plenty of racks list it as a feature even though it’s no longer unique to one gym. It sits alongside steel gauge and upright size as one of the details that separates a considered rack from a basic one.
Do you actually need it?
Treat it as a nice-to-have that tips a close decision, not a dealbreaker. If you bench in the rack and you’re particular about a perfect unrack and safeties set right at your chest, Westside spacing is worth seeking out — it removes the “stuck between two holes” annoyance for good. If you mainly squat, or you’re not fussy about the last inch of bench setup, standard 2-inch spacing is perfectly fine and shouldn’t stop you buying an otherwise better rack. When two racks are otherwise even, the one with Westside spacing is the more refined pick.
