Change plates where you need them.
Fractional plates have a way of ending up everywhere except where you're lifting. The Mag-Horn snaps onto any steel rack upright — no holes, no hardware, no rearranging — and gives your change plates a home right at the bar.
Three strong magnets lock it flat against the steel. It's conservatively rated for 10 lb of plates, and as the gallery shows, it'll hold a 25 lb plate without letting go.
A built-in bump guard sits between the Mag-Horn and your upright, so your rack's finish stays untouched no matter how many times you move it. And it moves a lot — that's the point. Squat day, bench day, whatever: pull it off, stick it where you're working, load it up.
The barrel is kept deliberately short — enough for a stack of change plates and fractional plates, without a foot of horn jutting into your walkway. A hex pattern wraps the underside of the barrel, adding grip texture where your plates rest with a clean, smooth finish up top.
Features
- Triple-magnet mount — three strong magnets hold it firm to any steel upright, tool-free
- 10 lb working load — shown holding a 25 lb plate in the gallery
- Built-in knurled bump guard — protects your rack's finish every time you mount or move it
- Custom accent colors — match the bump guard and FF logo to your setup
- Hex-pattern underside — premium aethstetic in every detail
- Minimal length — stores plates tight to the upright and out of your way
Works great on:
- Power rack and squat rack uprights (3x3, 3x2, 2x2 — any steel tube)
- Wall control boards and steel pegboard — perfect for organizing micro plates on the wall
- Any flat steel surface in your gym
Good to know: the magnets need magnetic steel to grip — the Mag-Horn won't hold on stainless steel or aluminum surfaces.

These are perfect for my change plates. Holds great on the rack and look super.
Magnets are strong. The Mag Horn is very attractive and provides me with the perfect change plate holder on my Weight Tree. Well made, decent price, great look, what's not to like!
Really love this super convenient product. I use it to hold some change plates and move it around the gym for different movements that I need it for. It’s nice to be able to store it on the rack and then move it closer to my deadlift platform when I need an extra pair change plates in one convenient place to put them instead of just throwing them on the floor.
Great solution, magnets are super strong, also just a cool looking product!
Top quality item. A great design and well made. Red and black looks great on my PR5000. Magnets are really strong. Quick delivery from the US to the UK. Would definitely recommend
