There are two Easyroll fridge trolleys, both rated 250kg: the Stair Climbers Fridge Trolley has three-wheel stair climbers and is the one for stairs, and the Heavy Duty Fridge Trolley runs 10-inch wheels on puncture-proof PU foam tyres for flat runs. Both ratchet-strap the appliance to the frame.
Each has a steel frame and ball bearing wheels, and a spare Easyroll Fridge Trolley Ratchet is sold separately. The trolley guide's types section covers fridge trolleys alongside sack and platform trolleys. Filter by load capacity to match your appliances.
