Hole spacing should be 1" x 2 1/4" to replace standard plastic blocks. Mine, in the larger size, was 2 3/8". If I installed this on a fresh install it might work, but not as a replacement. Apparently this was a very common problem - you would think the manufacturer would fix this would..Another problem is that the T-strap doesn't hook into the holder without some modifications. Shouldn't the manufacturer make a device that actually works? I'll use a different plastic door holder.
