Adjustable Aluminum Threshold Waterproof Hidden Screws Add-on Extension Available Heavy Duty Commercial and Residential, Multiple Sizes Available (Clear, 72 inch)

If you are replacing an old, ace hardware number placed there by morons who banked the slippery marble tile toward your house instead of away and hence made a regular mote out of the threshold... or if you have a 4' wide custom wood door from the 60s that bakes in the Arizona sun and tops put at 189 on hot days and freezes in the frigid winters down to 14° that has since become a little warped... then an adjustable threshold will make your life so much better.My handyman, who often works on luxury homes in Sedona and for the celebrities who own them...he loved this threshold. He got all the details so he can order this. It makes his job easy, often home owners don't want to cut down a door and he doesn't want to run a diagonal cut, this solves the problems and can meet in the middle of a cracked entryway or saggy door or out of plumb frame. All which happen with severe weather here.My threshold looks so stinking nice and the depth was perfect, like it was made for the house. We didn't even cut it down, it was an exact fit.So...get this and save on your time and labor for your next door...

The threshold looks great and is well built. I like the fact that the bottom is composite.I ran into an issue installing it, and was able to reach the customer service to resolve it. Overall the experience was very positive.One suggestion is to include a few extra hole plugs, in case additional holes need to be drilled on the adjustable cover.

Highly recommended this great thresholdLove the quality it looks good and fit perfectlyAppearance is superAnd great value for your moneyEasy installation!!!!!

I needed to cut it down to fit my application, but nice quality threshold. I also added an extension to make it wider that also fit well with this piece.

Great value for your money fits perfectly easy to assemble works great item is described

Quick shipping, quick customer service response

Adjustable Aluminum Threshold – 72"After much research, I couldn’t find another 6' adjustable threshold with as good a design or as attractive as this model. It appears to be the highest quality threshold on the market. That opinion didn’t change after it was installed.Pros:- Threshold uses a composite material underneath rather than wood, so it shouldn’t rot as my previous threshold did.- The eight adjusting screw openings/caps avoid the center of the PVC top rail on this 72" threshold, leaving free space to drill a hole for a vertical door locking bolt, which most double doors need. I had been worried about that.- Feels solid walking on it.- Looks great once installed.Cons:- At the intersection of the threshold’s bottom and the vertical PVC trim piece, the composite base is only 1/8" thick as it turns 90 degrees – an obvious failure point. On the threshold I received, the composite had broken at that point from the trim at one end. (I super-glued / clamped it.) Since that weakness traverses the 6' length of the trim, that entire piece of trim could snap off at any point; for example, with a hard collision on that side of the installed threshold. Plus, it has a gap between it and the threshold’s top rail, which would collect dust, debris, and bugs. To mitigate these issues, I applied silicone seal to that gap after adjusting the top rail up all the way. Thus sealed, no further height adjustment is possible.- The height adjustment screws are, ridiculously, zinc plated steel – which WILL rust out over time. Obviously, they should be stainless steel, which would only raise product cost by a buck or so.- As delivered, the top of the PVC top rail that sits under the door sweep is 1.25" above the floor. I raised it via the adjustment screws to just over 1-3/8", which is about as high as it will go. So much for “adjustable”. Much more than 1-3/8" and that PVC top rail would pop off of its side aluminum supports. A simple design change to that rail would allow for a greater adjustment.Other:- A 3" extension is sold, but my doorway doesn’t have 3". How about a short (e.g., 1") extension, to better finish the sloped side of the aluminum threshold. That’s what our previous threshold did and it looked fine...- No installation instructions are included, so you’re on your own. I installed the new threshold by bolting it to the concrete floor with 5/16" stainless steel lag screws and sealed all joints to prevent water intrusion into the room or under the new threshold.Summary:This is a very good threshold with a few areas needing improvement. Customer images are after the old threshold was removed and the surface cleaned – and after this threshold was installed.Installation details:Here’s how I installed it on concrete. If your floor isn’t concrete, this won’t apply.- thoroughly cleaned the concrete area where the threshold goes so that the silicone seal will stick.- drilled four 1/4" holes through the threshold face; 4.5" from the ends and 21" apart after that.- set the threshold in place over the doorway and clamp the ends from going into the room, to keep it from moving while drilling. My doors open inward...- drilled two 1/4" starter holes into the concrete, one at each end – using a rotary hammer. Drilled the holes at a 90 degree angle. Drilling on a slant will move the hole entrance towards that slant.- removed the threshold and drilled those holes out to ½", about 2" deep – blow holes clean with an air gun.- enlarged the threshold face holes to 5/16"; inserted ½" diameter lag shields for 5/16" lag screws into each concrete hole. One hole was slightly too loose, wrapped that lag shield with multiple layers of 2" wide aluminum duct tape – to make it tighter in the concrete hole.- temporarily attached the threshold using two 5/16" x 2.5" stainless steel lag screws, with large stainless washers and a large neoprene washer underneath. 3" lag screws also work. If an end doesn’t quite align properly, enlarge the threshold face hole just a bit so it could be adjusted – and retighten it being careful to not over-tighten, thereby crushing the aluminum.- in my case, the old threshold was 72-7/16" wide, so I filled the end gaps with PVC pieces cut from a 3/4" x 6" PVC board, about 3/16" thick, using a sliding compound saw.- drilled the remaining two starter holes into the concrete, removed the threshold and enlarged those holes to ½", repeated the above steps until the threshold was aligned and down for good. Dusted off the entire area using an air gun – a vacuum also works well.- ran a bead where the threshold and concrete meet using “GE Supreme Silicone Kitchen and Bath”, their best silicone seal. If the door frame is PVC, use the same seal at the threshold sides, otherwise, use a paintable (non-silicone) seal product.- forced silicone grease down on top of each adjusting screw through the PVC rail opening - to mitigate long-term rusting – cleaned the top rail and snapped the provided eight caps over those holes. (To remove those caps, pry off with a thin putty knife.)- after the threshold was installed, marked the spot where the vertical locking bolt for the locking door will slip into, drilled a 3/8" hole through the PVC, into the layers of aluminum, and due to a long bolt length, into the concrete below, using a 3/8" concrete bit.

Very easy to install but pricey.
