36" Brown Screenaway Door Review

I bought this door and decided to install it myself after watching their video. They have an 'easy installation' system.

I have no complaints about the door itself, although I just put it in so it's too early to tell if it will last.

But installing it is not easy. The instructions were very clear, but my complaint is with the hardware.

It comes with two rails, one for the side with the hinges and one for the side with the latch.

Both rails struck me as a little flimsy, considering the hinge rail will hold such a heavy door. But the real problem is that both rails are not 100% square.

Which means that when you screw it to your square frame of your house, one side of it pulls away from the frame. When I screwed in the hinge rail side, try as I might to get the rail to sit firmly against the frame, it kept pulling away. Took me a while to figure out it's because the rail isn't square. It was easier to get the top of the door in the right place, probably because they have you put that screw in with just the hinge rail before it is attached to the door. But as I went down the rail screwing it in, it got further and further off. The result was that the door did not hang straight. It had about 1/8 of an inch gap at the bottom.

Same on the latch rail side. Since I couldn't get the inside part of the latch rail to sit snugly against the frame, it means that the part of the rail that actually latches the door is too far towards the outside. Which means that in order to have the door fit snugly, I had to install the latch plate further in than the corresponding cut out in the latch rail, which leaves a little gap and looks stupid. And because the door wasn't hanging straight due to the other rail problem, I have about 1/4 gap at the top of the door.

Another complaint: the box says that it needs at least 1 inch of a mounting surface. I measured and I did have 1 inch on my frame. But the width of the latch rail is actually 1.5 inches. This means that about 1/4 of the opening where the latch goes is over empty air. Which I guess isn't a problem, except that's another reason why the latch plate doesn't line up totally with the latch opening on the rail.

The template they give you for drilling the holes for the handle is pretty close. But I did it very carefully according to instructions and one of the holes didn't line up exactly right with the hardware. Had to buy a file to try to fix it.

Also, I can't attest to this because I haven't had it long enough, but another review I read (for the 32 inch width) said that the closer is pneumatic instead of hydraulic, which means that it won't work if the temp is below 60 degrees. He said the only time the door didn't slam was in the summer. He finally got fed up and bought another closer for it.

Attaching the closer isn't easy either because you have to drill holes 1 inch from the top of the door which is too close to get any kind of power drill in there.

So between buying two spade bits for installation, a chisel for the dead bolt, a file to fix the drilled hole that didn't align, a drill bit (mine broke off), a screw extractor kit because I couldn't get my old door off without stripping the screws, and still having a door the doesn't hang right, I wish I had spent the $100 to have someone install it. They could worry about shimming the rails to account for them not being square. So much for the easy installation.

**after having the door in place for about a week now, I've found something else I don't like about it. On the outside, there's about 1/4 inch gap between the glass and the white metal trim piece in the middle of the door. I've found that dragonflies keep getting stuck in it. They fly against the glass and then fly downward and get stuck.

Incidentally, today when I was at a client's house I noticed they have a very similar door. It has the same hidden screen as this one. But it's made by Andersen. It does not have this big gap. They said they bought it at Home Depot and had them install it. Wish I had shopped around more instead of buying the first cool-looking door I saw (I got mine at Lowes).

Product Feature

• 17-4 PH stainless steel is a strong, tough material that offers greater corrosion resistance than 15-5 PH and can be heat treated at low temperatures after machining for high strength and hardness
• Meets ASTM 5643 specifications
• Ground with precision to the specified shape and size
• Standard tolerance

Product Description

The 17-4 PH stainless steel round rod has been ground, meets American Society for Testing and Materials International ASTM 5643 specifications, and has a standard tolerance. The 17-4 PH stainless steel grade is a strong, tough material that offers greater corrosion resistance than 15-5 PH and can be heat treated at low temperatures after machining to increase its strength and hardness. This material can be heat treated in lower temperatures than other heat-treatable stainless steels, reducing the likelihood of the material warping and scaling. A precipitation-hardening stainless steel, 17-4 PH is magnetic in its hardened state. The material was ground to achieve the precise shape, size, and surface finish.

Stainless steel is an iron alloy with resistance to staining and rusting in many environments where steel would typically degrade. The chemical composition of each grade creates a grain structure that falls into one of five classes: austenitic, duplex, ferritic, martensitic, and precipitation hardening. The austenitic class contains the most formable, weldable, and corrosion-resistant stainless steel grades, but they cannot be heat treated. The duplex class offers high resistance to pitting and chloride stress corrosion cracking. Duplex grades are heat treatable and roughly twice as strong as austenitic grades. The ferritic class contains moderately formable and corrosion-resistant grades compared to other stainless steel classes, but they cannot be heat treated. The martensitic class includes some of the hardest and strongest stainless steel grades that also offer mild corrosion resistance, high hardness, and good formability. Martensitic grades can be heat treated. The precipitation-hardening (PH) class can be heat treated after fabrication to achieve some of the highest hardness ratings in stainless steel.

Tensile strength, used to indicate the material� �s overall strength, is the peak stress it can withstand before it breaks. Corrosion resistance describes the material's ability to prevent deterioration caused by atmosphere, moisture, or other medium. Wear resistance indicates the ability to prevent surface damage caused by contact with other surfaces. Toughness describes the material's ability to absorb energy before breaking, while hardness (commonly measured as indentation hardness) describes its resistance to permanent surface deformation. Formability indicates how easily the material can be permanently shaped. Machinability describes how easily it can be cut, shaped, finished, or otherwise machined, while weldability characterizes the ability to be welded. Magnetism characterizes how much the material is repelled by or attracted to a magnet.

17-4 Stainless Steel Round Rod, Annealed/Ground, ASTM 5643, 0.9375" Diameter, 60" Length Review

I ordered this to replace a carbon steel axle shaft on a tractor-type lawn sprinkler. I checked it with a micrometer when it arrived. Perfect 7/16" diameter and had a nice finish. The fact that it is annealed was helpful when I had to drill some indentations for set screws.

CRATEX RUBBERIZED ABRASIVES POINTS BULLET 1X3/8 FINE BOX OF 100 Review

The Cratex bullets are an excellnt product and I have used them for many years. On this occasion though, several of them had holes that were too large to fit properly on the threaded mandrels. I contacted the folks at B2Bprofessionaltools and (after my server bounced their return messages back)got a phone call from Thomas on a Sunday afternoon! The emails and phone calls are prompt and VERY pleasant. Resolution to the problem is underway. I suppose this is less about the Cratex bullets than the fantastic folks at B2Bprofessionaltools. The abrasive bullets are a great product though. (I use them for quickly removing seams from polyurethane castings.) but I will definitely purchase items from this seller again. Thank you SO much!

Stearns "VR" Versatile Rescue Vest Review

I've used this PFD for numerous swiftwater rescues over the last few years. My crew always made fun of me for having such a fancy rig with all kinds of gadgets until Hurricane Irene came to town and I used EVERY tool I had with me. Now everybody's asking me where they can find this PFD. Lots of pockets and attachment points.

One issue.... Too many straps. This is not a vest you just slip on. It takes a minute or two to get the proper fit and tighten everything down just right. But if you're going to be operating all day in a flood zone or extended water ops, this is THE PFD to wear.
