Ghost Strong
Ghost Roller J-Cup
Fringe Sport’s Magpin replaces a rack attachment’s traditional spring-loaded hitch pin with a magnetic-cap pin, so accessories like landmines, dip bars, and safety arms stay seated without constant re-adjustment while still coming off with minimal effort. A stainless steel shaft resists rust in garage or basement humidity, and an anodized aluminum cap houses seven magnets tuned for a “Goldilocks” hold – secure enough to stay put, easy enough to reposition. A pierced nose accepts an included cotter pin for extra security when the magnet alone isn’t enough. It ships in 1” and 5/8” diameters with a 5.5” shaft (1” longer than the original version), backed by a lifetime warranty, and is compatible with all major squat rack brands. Fringe also sells a newer “Rhino Horn” Magpin redesign at a lower price point with further upgrades to the same stainless-shaft, magnetic-cap design.

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.
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.

| 4.5/5 | 4 reviews | u/Scottsdale_GarageGym recommends Fringe Sport Mag Pins by name as a step up from trailer-hitch-style pins, reporting no issues running two per side on a Rogue Monster rack. u/petekeller (Fringe Sport team member) confirms the original Magpin -> Rhino Horn redesign history and the 1"-longer shaft update matching the manufacturer page. No Fringe-specific complaints surfaced in the sample pulled. | |
| Youtube | 4.0/5 | 2 reviews | Carp's Gym (Rhino Horn variant): ranks Fringe's magnetic pins "second best" behind Oak Club and names them "best budget pick" -- stainless shaft, magnet fixed (not glued) into the head, cotter-pin security, works on most attachments. Flags loose/unprotected packaging (pins arrive nicked/dinged) and a usable shaft too short for lever-arm attachments. Fringe Sport's own Home Gym Con 2023 customer-testimonial clip is positive on magnet feel and security but brand-published, so weighted lightly. |
Fringe Sport’s Magpin swaps a rack attachment’s traditional hitch pin for a magnetic-cap pin with a cotter-pin backup, so accessories stay seated without constant re-adjustment. Its standout dimension is functionality: the magnetic hold combined with the pierced-tip security pin means no popped-out attachments and no fumbling with a spring-loaded hitch pin. The weak spot is build quality – Gray Matter Lifting’s multi-brand comparison rates Fringe’s 0.5 lb magnet strength merely “average” next to premium rivals like Exponent Edge and Vendetta, and flags that the knurled end caps unscrew and can loosen “if twisted to remove,” unlike competitors’ permanently-fixed caps. Value is strong, with bulk pricing scaling down toward $20/pin at the largest pack size, and GymRadar’s independently-notable 4.86/5 (31 reviews) backs up the mostly-positive expert and community read.
