SRTE Flying Fox Pulleys (Tyrolean Sheaves)-These pulleys were designed to be used as tyrolean sheaves; some models may also be used as conventional pulleys preventing your lines from tangling. These pulleys have extra karabiner holes for additional rigging, e.g., to control the speed and/or direction of the pulley, to act as a backup anchor point for the load.

SRTE Flying Fox Pulleys are available in Three different styles:

• Standard 'T' System -this has twin sheaves with four additional rigging points adding to the safety and control for the use. Le they can be rigged to control the speed and/or direction of the pulley or backup the main anchor point to the load. When used as a Flying Fox this pulley is perfectly balanced for a smooth ride.
• Standard 'I' System - (jockey wheel) this has a single sheave with one additional rigging point located in the centre of the cheek. Slings, karabiners, etc may be attached to this hold to aid safety and control. Ideal for use as a conventional pulley. When used as a Flying Fox this pulley will not be as balanced as either the 'T' or 'V' Systems (Note: it is the twin sheaves which aid balance).
• Revolutionary 'V' System - (triangle) this has twin sheaves with one additional rigging point. Unlike any other Flying Fox Pulley on the market, this pulley may double as a Conventional Double Block. As a double pulley you can use the pulley upside down (i.e. The rigging point at the top W refer to diagram). When used as a Flying Fox Pulley, this pulley is perfectly balanced for a smooth ride.
