SINGLE OR TWIN CYLINDERS 

The Contour 300 is for single cylinder operation, whilst the Contour 500 has two cylinder valveretainers; one of which rotates and the other is hinged to fold flat to the back plate when not inuse.  

Twin cylinder operation is achieved by using a high pressure manifold, connecting the twocylinders to the back plate with minimal movement.

The Contour 500 can therefore be used for either single or twin cylinder operation, whilst maintaining the set’s ergonomics.  

The Contour 300 & 500 series’ Kevlar webbing cylinder band is infinitely adjustable without any tools and the unique “over centre locking” cylinder band latch is easy and quick to use whilst offering full security.
