The RMG self tensioning drums allow for the elimination of tensioning devices in the sheeting system such as shock cord, rubber band material, hat elastic, springs etc. The spring loaded return spool in these drums takes up any slack and maintains a positive tension in the sheeting system.
32 mm and 42 mm ST Drums are available in Left and Right hand versions. If the winch drum turns clockwise (viewed from top of drum) to sheet OUT, the Right hand ST drum should be used. When the winch turns anticlockwise to sheet OUT the Left hand ST drums is used.
