Cripston is a distributor of life safety equipment for work-at-height and we care about your safety and the equipment you use. Heightec has recently released an important inspection statement regarding the heightec D42 Twist Chest Ascender. If you use this chest ascender, then please carefully read the inspection notice and comply with all requests to see if your heightec D42 Twist Chest Ascender meets the requirements for replacement. We recommend measuring the device as heightec states and checking the batch number on the device before sending it in because it may not qualify for replacement. Cripston customers can send their Twist to PMI or heightec for inspection and possible replacement if it meets the criteria stated in the notice by heightec.
