For fast, easy "hundred pack" transport on the job.
Only WECK gives you all the options! New Allbend lets you turn arcs and corners in 22 1/2° increments, or combine two blocks to make 45°. They mix beautifully with 4" x 8" or 8" x 8" blocks, or the WECK corner blocks that give you a true bull-nose, 90° corner.
New DoublEnds and WeckEnds give you partitions with open heads and jambs, or step-downs with no other border materials. Designs you've only dreamed about are happening! Let WECK give you the edge.
