Product review (1 stars): EZdock Dryer dock isn't for everyone.
I purchased this exact item from HD when making some renovations in the washroom and found the insert with the hose attached would not lock in the wall adapter. The tabs are not strong enough to grab into the groves of the wall unit. I also found that the mounting holes in the wall adapter were so close to the 4" hole cut in the wall that the screws had little if nothing to attach to - hole was exactly 4". The rim should have been at least another 1" in diameter and the mounting hose closer to the edge away from the throat of the tube. I used the dumb thing by drilling new holes in the rim and using anchors to set the screws, glued the insert into the wall unit and clamped the dryer hose. It would have been much better to simply use the extended portion on the vent tube but I had already cut it to the proper length. I do not recommend this Easy Dock.
