Price is for one assembly. Two assemblies are needed per joint.
The cabinet makers dowel is easier to fit than the pattern makers although not as accurate, with a clearance of 0.25mm (0.010").
Fitting Notes
These need to be supported from the rear so should be fitted into blind holes ( 7.5mm dia. x 12mm deep). The fitting method varies, depending on the thickness of the baseboard ends. In all cases the matching pair of baseboard ends should first be clamped together & pilot drilled right through, at about 3mm dia.
For baseboard ends of 12mm to 13mm thickness the holes should then be opened up to 7.5mm before they are separated. An additional plywood backer should then be fitted behind both holes.
Thicker ends should be pilot drilled as above, then separated before drilling blind holes in both faces at 7.5mm to a depth of 12mm.
For thinner ends, build up the thickness with an addition lamination on the inside face of the baseboard end around the area of the dowel, then proceed as above.
The dowels can the be either pressed or hammered into the baseboard end.
There is a difference in the ends of the female half, one has a slight external chamfer, this end should be inserted into the baseboard.
