Model Number: GRED18423BR
Ladder frame runner (or stringer)made from 18mm x 140mm x 3m planks, cut down lengthways, can be used to make either a long runner or cut into shorter sections as very low cost spacer blocks. Note that the runner will not always have a smooth rounded topsurface, since the middle third will always have a cut face. This part can be used as spacer blocks, or alternatively the wider 67mm runners can be used, or can be cut from the 140mm plank.
This runner is very flexibleand can be easily formed into aradius of 2'6" or greater. But once fixed into a frameworkof spacers it turns from a flexible material into a rigid structure which can bear a significant loading.
Note that the exact width can vary from 42mm slightly.
