Original Patented Stopper
Press the button on the handle to lock the wheels instantly. There is no need to bend down, and you can see at a glance whether the stopper is on or off.
It proves its worth on a swaying train, a slippery airport floor, or a sloped surface.
About 50%* Less Rolling Friction
Our originally developed wheel uses highly durable chrome steel bearings that keep rolling resistance to an absolute minimum, so it maneuvers smoothly with only a light touch, even on rough pavement.
*Based on rolling friction testing, compared with the 50 mm diameter casters commonly used on suitcases.
About 30% Quieter
The new grooved Silent Caster® reduces perceived rolling noise by approximately 30% compared with our conventional standard model. Combining stability with quiet operation, it rolls smoothly and lightly, making it ideal anywhere noise matters.
Quality Control
Rigorous in-house quality testing that drives our craftsmanship forward.
At Ace, we never compromise on quality. ATI, our quality control research institute at our Akabira factory in Hokkaido, conducts a wide range of rigorous tests to develop luggage our customers can rely on.
Beyond quality testing, ATI explores next-generation materials, features, and components. This ongoing research and development underpins the exceptional quality of every PROTECA product.
120 cm × 5 drops
With weight loaded inside, the case is dropped five times from a height of 120 cm (about 4 ft) to measure caster strength.
250 rotations
An abrasive stone is pressed against the shell material under a 1 kg (2.2 lb) load and rotated 250 times to test wear resistance.
5,000 lifts
With weight loaded inside, the case is jerked up by its handle 5,000 times to test the durability of the handle and lock.
16 km rolled
With weight loaded inside, the case is rolled a full 16 km (about 10 miles) to test caster durability.
7,500 cycles
The case is opened, closed, and locked 7,500 times to test the durability of the lock and hinges.
Tumble drum
With weight loaded inside, the case is tumbled in a giant drum lined with protrusions to test how it holds up to knocks and falls.
500 hours
The case is kept at about 40°C (104°F) and 85% humidity for 500 hours to test its quality.
40°C to −20°C
The case is left at 40°C (104°F) for 24 hours, then at −20°C (−4°F) for 24 hours. This cycle is repeated three times to test heat resistance.
