RX3 Center Post

Name: RX3 Center Post
Brand: Get RXd
Rating: 4.78 (3 reviews)

The RX3 Center Post is Get RXd’s fix for a recurring complaint from its own rack owners: there was no way to do lat pulldowns or chest-supported rows centered between the uprights without buying duplicate side-mount attachments. It’s an L-shaped stub of 11-gauge, 75x75mm steel tube that bolts to a single upright with two 1” (25mm) chrome pins and knurled nuts, landing a mounting surface dead center of the rack so pads and seats that normally hang off one post can pull from both weight stacks at once. Offset 1” (26mm) holes at 2” (50mm) spacing on all four faces let it carry the RX3 Optimus Pad, Lat Pulldown Seat, Seal Row Pad, and Lat Pull/Low Row Pad in various configurations. It measures 23” W x 15” H x 9” D, finished in black powder coat with a laser-cut logo plate. The two-hole mounting pattern is metric-only and geometrically centered for a 42” interior, so it fits Get RXd RX3 and Titan Fitness racks but will not mount to an imperial 3x3 rack at all. The post alone does nothing — it’s designed to carry a separate pad, seat, or roller attachment purchased on top of it.

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 RX3 Center Post is an L-shaped stub of 11-gauge, 75x75mm tube that bolts to one upright and lands a mounting surface dead center of the rack, so pads and seats that normally hang off a single post can finally sit in the middle and pull from both cable stacks. Functionality and value are the standout dimensions: The Jungle Gym Reviews calls it “their coolest, most unique, most functional and also the cheapest attachment that provides the most value,” and GymRadar’s small panel scores Value a perfect 5.00 against 4.67 for both Performance and Build Quality. Versatility is the weakest dimension, and it is a hard limit rather than a quibble — the two-hole mounting pattern is metric-only (1”/26mm holes at 50mm spacing, centered for a 42” interior), so it fits Get RXd RX3 and Titan racks and simply will not go on an imperial 3x3. Budget for the pads too: on its own the post does nothing, and the pieces it carries — the RX3 Optimus Pad, the RX3 Lat Pull and Low Row Pad, the RX3 Optimus Back Pad — each cost more than it does. Independent evidence is genuinely thin (three GymRadar ratings, two reviewer channels, no independent Reddit thread), so treat the enthusiasm as promising rather than proven.

+Functionality: solves a specific Get RXd owner complaint — centering lat pulldowns and chest-supported rows between the uprights without buying duplicate side-mount attachments (Get RXd CEO in r/homegym; The Jungle Gym Reviews).
+Value: at $120 base it is the cheapest genuinely function-adding attachment in the RX3 line, well under the $135-$200 pads it carries, and GymRadar's panel scores Value a perfect 5.00 out of 5 (Get RXd attachments price list; GymRadar).
+Build quality: 11-gauge 75x75mm tube with two 1-inch chrome pins and knurled tightening nuts; reviewers report no wobble under load, and a verified buyer says it holds a chest-supported row pad with heavy weight (manufacturer spec page; The Jungle Gym Reviews; Get RXd verified buyer, Feb 2026).
+Versatility: offset 26mm holes at 50mm spacing on all four faces let one post carry the seat, roller, seal-row and lat/low-row pads in several configurations, and owners have hung third-party gear such as a Voltra setup on it (manufacturer page; GymRadar reviewer Ben.R.C).
+Functionality: reviewers across three independent channels describe it as an idea nobody else is selling, with Maguire's Gym noting he has not seen another company make this (Maguire's Gym; GymRadar; Get RXd verified buyers).

−Versatility: metric-only fitment is the biggest catch — 1 inch (26mm) holes at 50mm spacing on 3x3 uprights, so it fits Get RXd RX3 and Titan Fitness racks but will not mount to imperial 3x3 racks at all, and it is geometrically centered for a 42 inch interior (The Jungle Gym Reviews).
−Functionality: there is no leave-it-mounted workflow — you have to pull the post off and rehang it to change arm height between exercises, and it plus the pads are heavy and awkward to store (The Jungle Gym Reviews; Maguire's Gym).
−Value: the post alone does nothing, so the real cost is the post plus a pad, and the Optimus Back Pad is only worth buying if you already own this post (Get RXd attachments price list; The Jungle Gym Reviews).
−Durability: little long-term data yet — the oldest recorded owner review dates to early 2026 and no source reports multi-year use, powder-coat wear or pin thread failures.
−Build quality: hardware varies by version — the configurator lists a Center Post Attachment 2.0 and one buyer bought a 1 inch bolt version, so confirm which generation ships before assuming a spec (Get RXd product page; Get RXd verified buyer, Feb 2026). Independent coverage is also thin and partly lukewarm — Maguire's Gym owns one and still reaches for a plain bench instead, calling the centered attachments too heavy and space-hungry for his gym (Maguire's Gym).
