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 are the usual timber nominal size that the 100mm Door Casing is machined from, with a finished size that is generally obtained;
Planed 4x1-1/2" Internal Redwood Door Casing sizes are generally ±1mm on thickness / ±2mm on width, ±6mm cross-cutting tolerance & there may be one splitter saw cut-edge; (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.)
