The main body also features drain holes along the rope path to allow grit and moisture to escape during use for better contact with the rope. Thicker body plates and a shaped connection point reduce wear on the device caused by shifting between the device and the connector (especially when used with steel connectors). This also keeps the device more in-line with the body during use. The opening mechanism is simple and secure with the ability to lock the device open for easier attachment and a removable pull cord that makes it easier to operate while wearing gloves. The proprietary rollers also allow the Turbochest to be rigged as a locking pulley for light hauling with a max load of 50 kg, 110 lbs.
