Commercial Smith Machine GM300

GravoMax GM300 Squat Rack + Smith Machine

GM300 combines a vertical Smith Machine with an open squat rack in one heavy-duty station. That means you can run guided work on the Smith side, then move straight into free lifting on the rack side without changing machines. For home gyms and commercial setups, it’s a clean way to keep training flow simple while still covering the essentials.

In short: if you’re comparing a Smith machine, a squat rack, or a Smith + squat rack combo in New Zealand, GM300 gives you both in one footprint.

How is it built?

GM300 uses 75 × 75mm steel uprights with a 3mm wall thickness for commercial-grade rigidity. The 185kg net weight helps the station stay planted during heavy sessions, while the vertical Smith path supports repeatable, controlled reps. It’s built to handle steady day-to-day use in both home and studio environments.

Why does a Smith + rack combo matter?

A combo station keeps your training organised. Use the Smith side when you want a fixed bar path and consistent tracking, then use the open rack side for classic barbell work with J-cups and spotter arms. As a result, you can structure sessions around control and free lifting without splitting your setup across multiple machines.

Why choose the GM300?

• Smith Machine + open rack in one station to save floor space
• Vertical Smith path for consistent bar tracking and repeatable sessions
• 20kg counterbalanced start weight for familiar loading
• 50mm Olympic sleeves to fit standard Olympic plates
• Clear load ratings: Smith 600kg | J-cups 300kg | spotters 300kg
• Anchoring option available if you prefer a fixed setup

How you’ll use it

Treat GM300 as two training zones in one frame. Run controlled sets on the Smith side, then use the free rack side for squats, presses, and other barbell work. This layout works well for solo training, coached sessions, and compact gym floors where you want clean movement between stations.

Height, clearance & anchoring

GM300 stands 2250mm tall. We recommend leaving extra ceiling clearance for comfortable setup and use. If you want a fixed feel (or you’re setting up for multiple users), ask us about bolting it down based on your floor type and usage needs.

Expand & Customise

GM300 sits within the GravoMax system. If you want to build the station out over time, choose compatible options from GM add-ons.
This approach keeps your base setup clean now, while leaving room to expand later.
