MIUONO 3x3 Weight Horn

Name: MIUONO 3x3 Weight Horn
Brand: Amazon
Rating: 3.78 (3 reviews)

MIUONO’s 3x3 Weight Horn is a bolt-on plate-storage peg for power racks and squat racks, sized to fit 2x2”, 3x3”, and 2x3” upright tubing through 1” holes. Each steel peg is built for 2” Olympic (50mm) plates or bumper plates and mounts with included screws and washers rather than a pin-and-lock design. Owners also use it as an improvised lever arm for loaded exercises, not just static storage. GymRadar owners rate it well on value but flag build quality and durability concerns under heavy loads: one review reports the horns bending when storing five or more 45 lb plates, and another notes sag on keyhole-style racks when fully loaded, so it suits light-to-moderate plate storage rather than a full 300+ lb set per side.

What is a Storage?

What gym storage is

Storage keeps a home gym safe, tidy, and usable: weight-plate trees and pegs, barbell holders (vertical or horizontal), dumbbell and kettlebell shelves, and wall or rack-mounted organizers. Loose plates and bars on the floor are a trip-and-damage hazard; storage reclaims space and protects your equipment.

What to consider

Match storage to what you own (plate diameter, number of bars, dumbbell count) and your space — wall-mounted units and rack-hung storage save floor area, while free-standing trees move easily. Check the weight capacity and, for wall units, that you can anchor into studs.

The MIUONO 3x3 Weight Horn is a budget plate-storage attachment that mounts to 2x2”, 3x3”, or 2x3” upright racks with 1” holes. Its standout dimension is value — GymRadar owners rate it 4.67/5 there, calling it a fair deal for the price — but build quality and durability are the weak points: one owner reports the horns bending under a full stack of five or more 45 lb plates, and another notes sag on keyhole-style racks when loaded heavy. Coverage is thin — just three GymRadar owner reviews and no independent editorial or video testing — so buyers planning to store a large set of heavy plates should treat this as light-to-moderate-duty rather than a heavy-gauge alternative.

+Value: GymRadar's independent sample rates it 4.67/5 on value, with owners calling it a fair deal for the price (GymRadar)
+Versatility: universal fit across 2x2", 3x3", and 2x3" upright racks with 1" holes covers most home-gym rack styles (manufacturer)
+Functionality: doubles as an adjustable lever arm for load exercises, not just static plate storage (GymRadar)

−Durability: one owner reports the horns bending when storing five or more 45 lb plates (GymRadar)
−Build quality: another owner notes plates can sag on keyhole-style racks when loaded heavy (GymRadar)
−Functionality: no independent editorial, video, or Reddit coverage exists yet — the only signal is a 3-review GymRadar sample (thin coverage)
