For decades, ambulance cots were secured with proprietary "antler-style" floor fasteners — hardware locked to a single cot brand, expensive to replace fleet-wide, and increasingly out of step with modern crash standards. Q'Straint's AMBULOK system was built to close that gap: a universal cot docking system that brings existing cots into compliance without replacing them.

This guide walks through how AMBULOK works, which bracket and base system to pair with your cot, and what to check before you order.

What Is AMBULOK?

AMBULOK is Q'Straint's docking system for ambulance and NEMT cot transport. Instead of a cot-specific fastener, AMBULOK uses a bracket that installs on the cot without permanent modification, then docks into OMNI Floor L-track already installed in the vehicle — the same track system used for four-point wheelchair tie-downs. That shared floor infrastructure is what makes AMBULOK practical: a vehicle already outfitted for wheelchair transport can add cot capability, and vice versa.

The system is engineered around EMS "muscle memory" — one-handed, tool-free engagement and release, with individual parts weighing 10 lbs. or less. Crews can transition a vehicle between cot and wheelchair configuration in minutes.

Why SAE J3027 Matters

SAE J3027, published in 2014, is the crash standard that reshaped ambulance cot securement. Testing that informed the standard found that older antler-rail cot fasteners allowed roughly 30 inches of forward cot movement in a simulated 30 mph frontal impact — enough force to break the cot free and send it into the patient compartment. SAE J3027 requires that forward excursion be limited to 14 inches, effectively phasing out antler-style systems industry-wide.

AMBULOK is engineered to meet SAE J3027 using securement technology adapted from Q'Straint's wheelchair tie-down systems. For a deeper look at how SAE J3027 relates to the broader CAAS GVS and NFPA 1917 ambulance standards, see our upcoming guide on ambulance cot securement standards.

The Four AMBULOK Components

An AMBULOK installation has two parts: a bracket that mounts to the cot, and a base system that installs in the vehicle floor. You need one of each.

Cot Compatibility

AMBULOK is built to work with cots already in service, not just new purchases. Confirmed compatible models include:

• Stryker Power-PRO XT (powered cot)
• Stryker Performance-PRO XT (manual cot)
• Ferno PowerFlex+ ST
• Ferno ProFlexx

If your fleet runs a different cot model, contact our specialists before ordering — we'd rather confirm fit than have you guess.

Buying Considerations

• Match the bracket to the cot type — powered cots need the Power Bracket (Q04BR201); manual cots need the Manual Bracket (Q04BR202)
• OMNI Floor L-track is a prerequisite — if your vehicle doesn't already have it installed, that's an additional project before AMBULOK can go in
• Electrical vs. mechanical is a workflow choice — electrical offers push-button convenience; mechanical avoids any wiring into the vehicle's electrical system
• Dual-use vehicles benefit most — a vehicle that alternates between cot transport and wheelchair transport gets full value from the tool-free, minutes-long configuration swap

Installation & Documentation

Each AMBULOK component ships with a manufacturer installation manual, and brochure/comparison materials are available to help you spec a fleet-wide order. Installation should be performed by a qualified technician familiar with OMNI Floor L-track systems — this isn't a bolt-it-yourself product given its role in crash protection.
