Fourth Element Si-Tech QCP XL Round Cuff Rings & Silicone Wrist Seals System is meant for bigger hands that simply cannot fit through the oval rings.
The rings are quick and easy to exchange, which is a great feature when the suit needs to have different sizes of seals or you have ripped a seal -just a few minutes and the new seals will be fitted.
The PU rings can be glued on to the inside of the drysuits sleeves. Although not difficult to-do, the correct adhesives (polyurethane based) must be used. The circumference (of the oval) of the section that is glued is 32.2cm, ensure that the end of the drysuit matches this. This enables your wrist seals to be easily changed at the dive site.
The system can also be fitted to latex seals already glued on to a drysuit to enable you to click on the Antares glove ring system with dry gloves.
