This review is for the DreamLine Duet 56-60 in. W x 72 in. H in Brushed Nickel.
The door was easy to install and beautifully finished. All parts are labeled with an ID number and logically packaged into multiple plastic bags related to the install step.
Customer service is top-notch !! I broke an expensive part and called to purchase a replacement. They shipped me a new part free of charge to ensure I would be happy with my new door. This company knows how to treat customers !!!! Since they sell tons of these doors, customer service is typically busy....don't wait on the phone, leave your phone number and they typically call back within an hour.
Some helpful hints from my self-install:
1. Read the entire installation manual before starting.
2. If your 3 wall width measurements (step #1) are nearly identical and wider than 56", cut off an additional 1/8" width from the top and bottom rails (not just the 2 1/4" in step #2). If your walls are nearly exact as mine are, you will have difficulty keeping the silicone on one wall profile (part #2) without the extra 1/8". The 1/8" is absorbed in step #7 (see below).
3.(Step #2) You only need to cut 1 end of the UPPER guide rail since there are no alignment holes to consider. However, the top of the rail is rather thick and the rail is a few inches tall. If using a hacksaw to cut it, be sure to make your cut perfectly straight else you will see the crooked cut after the unit is installed. I cut mine on a 10" radial arm saw with a 60 tooth carbide tip blade for a perfectly straight cut, then polished the ends with a fine flat file. A chop saw with that blade will work fine too if properly secured.
4.(Step #3) I would not attempt to install those screws with a hand-held screwdriver as you will likely strip the head before the screw is fully seated. Use a screw gun and #2 philips bit, or much better - take a trip to the hardware store and buy stainless steel hex head screws of the same size and install them with a 6 point socket.
5.(Step 6) If you built your shower new and have studs/wood behind the screw holes, don't use the wall anchors. Use stainless steel screws directly into the wood. Ensure the screws penetrate the wood at least 1/2". Typically, a 1 1/2" screw will accomplish this (pre-drill a smaller hole).
6.(Step #7) Apply the clear silicone to the WALLS and shower base THRESHOLD, applying a thicker layer on the wall with the shower head. Move the entire frame into the opening on an angle, shower wall in first, and 3/4" to 1" above the base threshold. After sliding the side opposite the shower head into place, push the entire assembly down on top of the shower base threshold, then check for vertical level and install screws. Wipe off any excess silicone then wipe it clean with rubbing alcohol on a paper towel immediately.
7. (Step 8) There is a designed small amount of play when attaching the rollers to the top of the glass doors. When attaching the rollers, pull up on the rollers so any extra space is between the top of the glass and the roller. This will make the door sit as low as possible and minimize the chance that water will splash on the bottom rail and leave drops of water on the bath floor (yes, I have this issue). Also make sure both screws of every roller are positioned the same (pulled up) - if one side is pulled up and the other is not in the same position, the door will not hang straight....it will not scrape on the bottom rail but it will hang on an angle that is highly noticeable where the 2 doors meet in the middle. You cannot adjust this without removing the doors from the track.
8. (Step 9) This step should be accomplished with 2 people, especially when installing door B (the inside door).
Hope this Helps!
