A Double Chamber meets the requirements for the removal of textured coatings. Using SpeedClips™ a double chamber can quickly and easily be attached to a triple chamber airlock to form a bag lock, where space is limited.

The SpeedDock™ double airlocks are designed for three different applications:

- For low risk environments where a triple airlock is not required.

- For combining with a single chamber SpeedDock™ in order to create   a dog-leg configuration.

- For use as a bag lock, all but the first flap are double-welded into   place to help avoid the need for ‘patch-ups’ during heavy use.

The first flap is supplied loose but with heavy duty double-sided tape ready to secure in place. It can be positioned on any of the 3 sides of the entry chamber (see diagram)  It comes in three chamber sizes to fit 100cm, 74cm or 60cm speed frame cubes.

Note that the HSE requires that, wherever possible, a 100cm size should be used.
