Product Details — ACE-SD2112-4870-B


1. Safety Comes First


  • ANSI-Certified Tempered Glass

6-mm (1/4-inch) thick heat-treated glass, rated for impact. Built for daily use.

  • Explosion-Proof Film

Should your glass somehow shatter, no fragments will scatter anywhere and it offers the safest protection. And yes, we'll ship you a new door if and when it does.

  • Precision Glass Engineering

Advanced CNC equipment ensures even glass hole spacing with no edge drilling—improves strength and reduces break risk.

2. Engineered to Retain Water Where It Belongs


  • 97° Bottom Threshold Seal

Creates a low, crisp angle for water to follow and gets that pesky water onto the base and down the drain.

  • Edge Sealing Strips

Glass gets a full-length buffer for movement sound, and you get complete protection from splashes.

  • Wall-to-Glass Flush Fit

Unlike regular bumpers, we do not leave any nook or cranny for wall gaps and leakage reasons.

3. Structure You Can Rely On


  • Longer Guide Block

It holds glass more securely for increased stability. Less wobble = safer sliding.

  • Top Rail Stability 

Durable aluminum top rail offers strength and rigidity to the door to help ensure smooth operation.

  • 304 Stainless Steel Hardware

Handles, screws, and fasteners have a corrosion-resistant and rust-resistant finish—longer than similar voltage detectors in wet environments.

  • Smooth Rounded Edges

All aluminum profiles are polished and rounded preventing anyone from being injured while installed or in use.

4. DIY-Friendly, Installer-Approved


  • Hardware Kit & Complete Manual Included

It comes with everything you need including photo step-by-step instructions. Ideal for DIY or contractors.

  • Vertical Adjustment (1/4")

The built-in eccentric rollers allow you to adjust alignment on uneven walls.

  • Aluminum Wall Cap for Coverage

Black wall guard prevents imperfections with a black trim that provides an enhanced water barrier and a finished look.

  • 4-Roller Sliding System

Durable plastic pulleys ensure quiet, effortless glide with low friction and no derailment.

Measure the doorways leading up to your bathroom to ensure you can carry the shower door through your house without damaging the glass. Make sure there is room to turn your shower door if necessary.

What You Will Need

  • At least two people
  • Tape measure
  • Pen & paper
  • Level

Step 1: Make a Sketch of Your Shower


With your pen and paper, sketch a small diagram of your shower. Use this visual reference to label your measurements.


Take each measurement twice, and if your numbers differ, go with the larger one. Always round to the nearest 1/16ʺ for accuracy. If you opt for a custom shower door, knowing precisely how to measure for a glass shower door is even more essential.

Step 2: Measure the Width


Using your tape measure, measure the width of your shower from one side of the wall to the other. Measure the width in three spots – along the base, middle, and top. See Image 1.

If you have a neo-angle shower, measure the width in sections along the base of the shower pan. See Image 2.

Step 3: Check if the Walls Are Plumb


Older homes or showers may not have walls that are perfectly straight. If your wall is plumb, meaning straight up and down, you should have a worry-free shower door installation. If your walls are not plumb, you should seek the help of a professional when installing your shower door. To check if your shower walls are plumb, place your level flat against each shower wall. Look at the bubble on the level and see if it is centered between the two indication lines. If the bubble is centered, the wall is plumb. If the bubble is not centered, angle the level away from the wall until it is. Holding the level in this position, mark the distance between the wall and the level on your measurement sheet. Share these measurements with the professional who will be installing your shower door. Do this at the bottom and top of each wall to ensure they are plumb all the way up. See Image 3 below.

Step 4: Measure the Height


Measure the distance from the base of your shower to its top. If your shower door will rest on a threshold, have your measurement begin at the top of this "base.” See Image 4. If your desired shower door size is shorter than your shower's overall height, only measure up to this point. See Image 5.

Step 5: Measure the Opening


If your new shower door will be the same style as your current door, measure the width of the current door and use that measurement as a reference. If your new door will sit over a section of the threshold that you have previously measured, use this width. See Image 6. If your shower door will be smaller than your threshold's width, measure your desired width. An example would be a fixed shower door that only covers three-fourths of your threshold's overall width. See Image 7.

If your new door will swing outward (hinged, pivot, or folding doors), take your tape measure and make it the desired width of your shower door, then place one end of the tape measure where the door's hinge would be. Holding it in place, pull the tape measure in a semicircular motion. This will determine if there is sufficient room for it to open without hitting a wall, door, or vanity. See Image 8.

Very clean/modern look and super thick glass!

I received my package, but unfortunately, it arrived damaged. However, after reaching out to customer service, they were incredibly helpful and responsive. They quickly resolved the issue and arranged for a replacement to be sent out right away. The service was excellent, and I really appreciate their prompt action. Great customer support and a seamless experience in the end!

Clean and modern, well made

Well made, easy enough to assemble. Glass is very solid. Doors are about 50 lbs each and 6 foot tall, so you will need two people to move them around and install them. You could do it alone, but it's much better to have help. Came with mounting hardware; I used some of their hardware and substituted some of my own to get longer screws directly into studs. Finished installation looks very clean and modern.

Great looking DIY shower door on a tight budget

This was a 2 day install (allowing the sealant to cure on the base rail before installing the rest of the frame) by 2 people but it looks great and seems to be good quality. The box was very heavy and had a huge gash in with an area of crushed foam but it was really well packed and the glass was still intact. Can’t speak much on durability/longevity but for a DIY shower door this is a good buy. It was easy enough to install ourselves.

Nice Product-Zero Seller Support

With eventual support from Amazon, we had to re-order this as the first order...vanished and never arrived. Seller never responded, UPS tracking was frozen and of no help. The price seems pretty good. The box is extremely heavy. Extremely! Simple construction. Simple installation. Looks good. Slides easy and has clear "bumpers" around the glass door edges for safety. Yes, water beads to the glass, but that is common and fixable. Don't appreciate the Seller, but the product seems good. Don't forget to clear-caulk the edges.
