5" PEFC Redwood Casing is a natural product - variations in knots, colour and grain should be expected - This is not a defect.

4x1.5" Planed Timber Internal Casing should be treated and fixed in place as soon as possible to help minimise any movement/­twisting and surface checking/­splitting that occurs naturally with changes in moisture content; 4" Softwood Internal Door Casings are not recommended for external use; External use of Moulded Redwood Door Casing is at your own risk - Timber life expectancy is increased with good timber treatment and protective finishing coats. It is better to use pressure treated timbers externally.

- Sizes measured as at - 14/12/2012 -

Sizes are the usual timber nominal size that the 125mm Door Casing is machined from, with a finished size that is generally obtained;
Planed 5x1-1/2" Internal Redwood Door Casing sizes are generally ±1mm on thickness / ±2mm on width with one splitter saw edge & ±6mm cross-cutting tolerance although - be aware: For a multitude of reasons, size and profile of timber may vary from batch to batch, so it is best to purchase all you need for a job in one go, rather than buying more at a later date.

- We cannot be held responsible for any variations in machined timber sizes, pattern, grading, moisture content, treatment or certi­fica­tion;
- If it is important, then you need to check these or any other details before commencing work.
