Are Lozier, Madix, and Streater gondola parts interchangeable?
Updated July 15, 2026 · Pacific Retail Fixtures
Treat the major gondola brands as NOT structurally interchangeable. Upright slot patterns, bracket geometry, and base-shoe connections differ between systems — some parts appear to fit, but a bracket that seats 90% of the way into a foreign upright is a shelf failure waiting for weight. Streater-style uprights (diamond-shaped perforations) are definitively incompatible with round-slot systems. If you are extending or repairing a run, identify the brand first and match it — or stand a separate new run beside it.
Why the internet disagrees about this
You will find forum posts swearing shelves swap fine between brands, and listings advertising "98% compatibility." Both can be half-true: a shelf resting on two brackets may sit in a foreign system while the connection was never designed for it — different slot pitch, tab thickness, and lock geometry change how load transfers to the upright. It holds until it is front-loaded, bumped by a cart, or stacked to rating. Structural mixing is a risk you cannot see until it fails.
Identify what you already have
- •Look at the upright perforations — diamond-shaped punchouts indicate a Streater-style system; rounded or rectangular slots indicate Lozier/Madix-style systems.
- •Check the top caps and end trim — manufacturers stamp or emboss their name on upright caps or metal end covers.
- •Measure slot spacing — matching systems match exactly, not approximately.
- •Photograph a bracket — the hook profile is the fingerprint; any competent fixture dealer can identify a system from a clear photo of the upright slots and a bracket.
What actually is safe to mix
- •Pegboard accessories — standard peg hooks on 1-inch-center pegboard fit regardless of whose frame holds the board.
- •Loose merchandising accessories — baskets, sign holders, and shelf-mounted dividers that clip to the shelf (not the upright) travel between brands.
- •Complete runs side by side — a run of brand A standing next to a run of brand B is fine; problems start when parts cross between them mid-run.
Buying used? Do this first
Before buying a liquidation lot, photograph the upright slots, a bracket, and any stamped caps — and confirm the lot is ONE system. Mixed-brand lots are the most common used-shelving regret: half the parts will not build a complete run.
Every part in our runs is one system — add sections years later and they fit.
Related questions
Will Lozier shelves fit Madix uprights?
Some appear to seat, but the systems differ in slot and bracket geometry and neither manufacturer supports mixing. Do not hang rated loads on a cross-brand connection.
How do I tell what brand my shelving is?
Check for a stamped name on the upright top caps or end trim, then look at the perforation shape: diamond punchouts indicate Streater-style; round or rectangular slots indicate Lozier/Madix-style. A photo of the slots plus a bracket is enough for a dealer to identify it.
Can I extend an existing run with new shelving?
Only with the same system. If the brand is unidentifiable or discontinued, extend with a separate freestanding run beside it rather than joining foreign uprights.
