I have a customer with bedroom sets manufactured by Henry Link and Young-Hinkle. The furniture is approximately 30 years old. The wood center rail that the drawer is guided by has deteriorated on three drawers. The wood appears to be poplar. I measured a sample and it is 16" long, 1-1/16" wide, and 11/16" thick. The center of the back hole for securing the rail to the framing is 3/8" from the back end of the piece. The center of the front hole for securing the rail to the framing is 9/16" from the front end of the piece. There is a channel on each side of the wood rail. It begins 1/8" from the bottom of the rail, the channel is 5/32" to 3/16" wide and and 1/4" deep. The top of the wood rail has two machined side guides (part of the one-piece wood rail) that are rounded on top, are 5/32" wide, and stick up 1/8", running the entire length of the piece. At the front of this rail, stapled between these guides, is a tan, plastic bumper that is 3/4" long and 3/8" wide. It is 3/8" back from the center line of the front hole. It sticks up just slightly higher than the side guides. Are replacements for these available?
