Don Moody of Handyman Reality explaining his own method of door selection, sizing and installation of pre-humg doors from @homedepotcanada and including using a bifold door to create custom 18" wide doors installed with pre-manufactured frames.

Special thanks to Eddy Kusiak Millwork Specialist
Strathcona @Home Depot Canada He picked the doors quickly & perfectly from my list.

Shout out to Hallmark Doors of Edmonton Alberta Canada for its fine custom closet door manufacturing.
