PSA18/48 Four Tier Shelving Add-on Kit

The Modular Systems PSA18/48 is a four-tier add-on shelving kit measuring 1220 × 455 × 1800 mm that extends an existing Modular Systems PSU shelving bay. It supplies four more vented, polypropylene-coated steel shelves with one set of posts (one side only), bolting onto a standing PSU kit to build a longer run of rust-free storage for cool rooms, cold stores and dry stores in cafes, restaurants and catering kitchens (1220 × 455 × 1800 mm, polypropylene-coated steel, four tiers).

Why operators choose the PSA18/48

• Extends your run — adds four more vented shelves to an existing Modular Systems PSU bay so you gain storage without a whole new unit.
• One-side add-on — ships with shelves and a single set of posts (one side only) that share the standing kit's end frame.
• Rust-free build — polypropylene-coated steel shrugs off moisture and won't corrode in cool rooms or wash-down areas.
• Wet or dry storage — vented shelves let air move and water drain, so it suits cold stores, dry stores and prep zones alike.
• Adjustable tiers — shelf heights reconfigure to fit tall stock, tubs and GN pans as your needs change.
• Backed by warranty — covered by 2 years parts only for commercial peace of mind.

Specifications

Venue suitability

The PSA18/48 suits operators who already run a Modular Systems PSU bay and want to extend it by 1220mm without buying a second standalone unit. It is an add-on kit, so it needs an existing PSU shelving kit to attach to rather than standing on its own.

Installation & delivery

The PSA18/48 assembles without tools and attaches to an existing PSU bay — the shelves and posts clip on and adjust to the heights you need. It ships flat, packed to 450 × 605 × 162 mm, so it moves easily through doorways and into cool rooms before assembly. Dispatched from our Sydney HQ with partner warehouses in Melbourne, Brisbane, Adelaide and Perth for faster delivery Australia-wide. Warranty is 2 years parts only; see our warranty information for full details.
