General Product Information

How we measure lids

When we measure a lid we always quote the hinged side (W) first followed by length. Length (L) is hinge hole centre line to front edge.

Side Hinged Lids / Doors

Dimensions of lids on the detail pages of the website are always shown as "Hinge Hole Centre to Front" (Length or L) and Overall Width of Lid" (W). In the case of Side Hinged Lids and Doors, this may appear pictorially wrong but allows for consistency in measuring.

Thermal expansion and lid manufacturing tolerances

Please be aware that all plastic lids will shrink and expand at slightly different rates than a metal container and so when fitting lids in extreme hot or cold climates, this will need to be a consideration along with the normal manufacturing tolerances of the products.

The tolerances we work to are as follows:

  • All lid customer drawing dimensions are measured at 17°C.
  • Manufactured size stated could be ±6mm per 1000mm length.
  • Thermal expansion of our plastic is ±2mm / 10°C / 1000mm length.


So a 1000mm square lid at 17°C temperature could measure between 994mm and 1006mm.
If the temperature dropped to -3°C (20°C drop) it could be between 990mm and 1002mm.
And if the temperature increased to 37°C (20°C rise) it could measure between 998mm and 1010mm.

Please note: This is especially important when fitting pairs of lids together.


Our Lid Recycling Scheme

Any scrap lids in your backyard? Looking for best practice and best value? All of our lids can be reprocessed and this recycled material can then be used to manufacture new lids.

Find out more about our Recycling Scheme and look out for this symbol which indicates that this lid type is available in recycled material.
