A.Washington_ lumber dealer has developed a unique and inexpensive door constructed from large panels of-fir plywood applied to simple shoring and a cbnventional barn door track. The door opens-far enough to allow loaded trucks to enter and leave the firmis carDentrv shop yet-closes tightly enough to retain heat in the shof. Designed and built by Carl Erickson, carpenter for Keen & Howard Lumber - Company, Centralii, Washington, the door simulates an accordion's folding action-and opens and closes with the flick of a wrist.

Erickson estimates his door can be constructed ancl hung by two men in about six hours for $55. The door can be modified to any size. ft's an idea equally adaptable lo -"rry.farm or warehouse-wherever a high-or particu- larly wide door is necessary.

The door consists of four hinged sections which slide open to one end while folding closed at the other end. Three of the sections consist of 4x10-foot panels of %i"9\ !t ply_wood; the fourth section is a panel ripped'to 2x10-foot dimensions. This end section is-later hiir!.ed to a d-ouble ZxQ jamb. All sections combined span l4-feet.

of two 9-foot 8-inch stiles, two 4foot top and bottom rails, and 3-foot 4-inch middle rail. Framing for the 2x10foot end section is a proportional equivalent of the 4x10foot main sections. All r-ails and stiies were butt-jointed.

The fir plywood panels were applied with 5d box nails every S-inches. Four sets of 4-inch strap hinges were fastened with fu-inch No. 6 wood screws at 6ach sectional joint.

__Th9 hinges were- alternated at every other door joint. The first set was fastened to the exposed framing, the next set to the paneled framing, and so on. Thus, as the doors are slid open, the alternated hinge sections fold together at the other end like an accordion.

The entire door is.mounted on a National No. 51 barn door track, with two swivel type trollev hansers. The trolleys were fastened to the fiont and end dodr section framing and blocked with 8-inch pieces aI 2x4. The barn door track was fastened to a double 2x6 header.

-An ordinary trunb clasp was fastened across the joint of the first two sections. Thus, when the door was ihut. the clasp locked these two sections together as a unit and prevented the entire door from buckling.

NIRB Enters Boycott Order Agoinst Corpenters Union

The NLRB has entered- an order against the Carpenters IJnion prohibiting them from inducing their mem6ers to refuse to handle products of any manufacturer because the_products do not bear the carpenters label.

Charges in the case (NLRB-No. 13-cc-157) were filed with the National Labor Relations Board bv tire Andersen p_orporation.of Bayport, Minnesota, against'the Carpenters Union in Chicago, both Local and International. The Union had applied its boycott against the use of Andersen windows in a large housing project in Hinsdale, Illinois. C. Bovd Mahin, of the firm of Macleish, Price & Underwood -of Cl{cago, was the attorney for Andersen.

The case is of major significance because it is expected to_ correct a boycott condition which has prevailed ln the Chicago construction area for many yeirs. The order
