All tricklevent colours are available boxed as bagged sets or bulk packed “pick n mix”.

Bagged sets – The vent (internal) and canopy (external) are bagged and are both the same colour, normally 50 sets per box.

Benefit; Sets are easy to pick and ship with each window. Typically, vents can be taped to windows or added to the hardware box that accompanies each delivery.

Colour on white sets – The vent (internal) and canopy (external) are sold as sets (white internal vent with a coloured external canopy), normally 50 sets per box.

Benefit: No need to buy two sets of vents, (a white set and a colour set) then dispose of the excess parts, so half price?

Specials – If you need a particular colour mix, these are normally made to order with 50 bagged sets per box. Contact customer service for advice on availability.

Bulk packed – The vent (internal) or canopy (external) are sold separately (one colour only), normally 100 parts per box.

Benefit: This allows for a “pick n mix” option on the production line. This allows more effective purchasing on volumes and “special” colours whilst being easily adaptable for colour on white. Buy more of the colours you use most of at better prices and carry minimal stocks of low volume use or special colours.
