The plastic filter prevents blockage of valves caused by dirt.

The filter is designed so that the top rim is levelled with the bench tray top. This way pots can be placed directly on top of the filter, and this way the whole area for the tray top is utilized.

The filter fits all types of trays - except for 330.3, 435.4 & 630.4


Stål & Plast A/S produces a glue specially developed for gluing of the bench trays.

The glue is delivered in the following sizes:

  • 2,5 - 5 - 10 - 20 litre buckets
  • 300 ml. tubes

It is important to NOT use an excessive amount of glue which can damage the trays.

For further information about use of the glue please see the installment guide.
