Rogue Bench Prop - Monster Series

Name: Rogue Bench Prop - Monster Series
Brand: Rogue Fitness
Rating: 4.78 (3 reviews)

The Rogue Bench Prop is a bolt-on crossmember for Monster Series power racks, designed with powerlifter and trainer Brandon Campbell Diamond to solve a common annoyance: getting a bench perfectly centered under the bar the same way on every setup. It mounts to the rack’s lower crossmembers with two 1” Monster detent pins, and a UHMW-lined channel then guides the bench’s front leg into a repeatable, adjustable position – reviewers report the whole mount takes under a minute. Built from 3x3” 11-gauge steel tubing with 7-gauge formed end plates, it also doubles as a general-purpose crossmember for dip handles, storage posts, or band-peg grip attachments when unhooked from bench duty, and adds real rigidity to racks that aren’t bolted to the floor. It’s compatible with most of Rogue’s own bench lineup (Bolt-Together, Flat Utility 2.0, Fold Up Utility, Monster Utility 2.0, Adjustable 2.0/3.0) but explicitly not with the older AB-2 or AB-3 Adjustable Benches, and works exclusively with Monster Series racks.

What is a Rack Attachment?

What rack attachments are

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.

Compatibility comes first

An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.

The Rogue Bench Prop earns strong, consistent praise from the two independent owner reviews available for solving a genuinely annoying problem – centering a bench under the bar the same way every time – with heavy-gauge steel construction. Functionality is the standout: both reviewers confirm it locks a bench into a repeatable position in under a minute and note it doubles as a general-purpose Monster-rack crossmember for dip handles, band pegs, and grip attachments once the bench is unhooked. Value is the weakest dimension – at $205 for the base crossmember alone (more with the optional Monster Mini Feet and spotter deck), reviewers agree it’s expensive for what is, at its core, a single cross-beam, and one owner reports the powder coat visibly chipping where the bracket meets the bench leg.

+Functionality: locks a bench into the exact same centered position under the bar every time, eliminating the usual minutes of trial-and-error adjustment (YouTube: Chip Burti; YouTube: Basement Brandon)
+Functionality: doubles as a general Monster-rack crossmember for dip handles, storage posts, and band-peg grip attachments once detached from bench duty (YouTube: Chip Burti)
+Build quality: 3x3" 11-gauge steel tubing with 7-gauge end plates and UHMW plastic lining that protects both the rack's powder coat and the bench leg (manufacturer product page; YouTube: Basement Brandon)
+Versatility: adjustable mounting position lets the bench sit at different depths relative to the bar, and it works with most of Rogue's own bench lineup plus reports of fitting some third-party benches (YouTube: Basement Brandon)
+Functionality: adding the crossmember measurably tightens rack rigidity by holding the uprights at their correct spacing, especially useful on racks that aren't bolted to the floor (YouTube: Basement Brandon)

−Value: expensive for a single cross-beam -- $205 for the crossmember alone, with the optional Monster Mini Feet and spotter deck pushing a full setup toward $375+ (manufacturer product page; YouTube: Basement Brandon)
−Build quality: the powder coating on the mounting bracket has started chipping where the bench repeatedly contacts it, even when centering isn't perfect every rep (YouTube: Basement Brandon)
−Versatility: exclusive to Monster Series racks (43" wide) and explicitly NOT compatible with the AB-2 or AB-3 Adjustable Bench, so buyers on other rack lines or bench models get no use from it (manufacturer product page)
−Functionality: a fully kitted-out setup (crossmember plus mini feet plus spotter deck) is heavy and not especially easy to move around once assembled (YouTube: Basement Brandon)
−Durability: no long-term wear reports beyond the paint-chipping issue noted above -- coverage is limited to early-ownership reviews, not years-in reporting (across gathered sources)
