Overview

The design of Thermo-Rite fireplace enclosures is notable for their attention to detail which results in ease of installation, trouble-free operation, and timeless beauty… Every aspect of Thermo-Rite products… from design and manufacture… to assembly… final inspection…and packaging is monitored and controlled at our modern Akron facility to ensure easy, convenient installation, superior performance, and lasting beauty.

Thermo-Rite: A History of Excellence

Every Thermo-Rite product, without exception, is made in the U.S.A. Since 1942, the name Thermo-Rite has stood for elegance, quality, and superior craftsmanship in glass fireplace enclosures.

Founded in 1942 in Akron, Ohio, Thermo-RiteManufacturing originated the tempered glass fireplace enclosure. In fact, Thermo-Rite was awarded the first United States patent for tempered glass fireplace enclosures… a patent held exclusively by Thermo-Rite from 1946 to 1963. Even today, every Thermo-Rite product…without exception…is produced in our Akron, Ohio facility. From our founding to the present, Thermo-Rite has been a market pacesetter.

We began as a custom masonry door maker. Through continuous innovation, we were soon leading the industry in the production and popularization of high-quality stock fireplace doors. Over the years, Thermo-Rite evolved with a wide and varied offering of models, styles, and sizes to satisfy your customers’ needs for glass doors on custom masonry fireplaces, stock masonry fireplaces, and many zero-clearance fireplaces. To please even the most discriminating customer, Thermo-Rite offers the industry’s largest in-stock selection of distinctive styles and finishes with a wide range of sizes to fit any décor and application.

If a stock door just won’t do, Thermo-Rite can custom-make a glass fireplace enclosure to suit any specifications. Like our stock fireplace enclosures, our custom-made fireplace enclosure options include anodized aluminum, steel, solid brass, and brass-plated steel. Thermo-Rite makes glass fireplace enclosures… exclusively. This single product focus enables us to offer quality fireplace enclosures… priced competitively…with on-time delivery… and, most importantly, service after-the-sale. Another guiding principle that sets Thermo-Rite apart is its uncompromising commitment to quality materials and precision manufacturing.

The design of Thermo-Rite fireplace enclosures is notable for their attention to detail which results in ease of installation, trouble-free operation, and timeless beauty… Every aspect of Thermo-Rite products… from design and manufacture… to assembly… final inspection…and packaging is monitored and controlled at our modern Akron facility to ensure easy, convenient installation, superior performance, and lasting beauty.

 


Description

Thermo-Rite’s stock Z-Doors are made as inside fits. We use Air Studs™ or an Air Draft Bar™ to elevate the frame so that it maintains the cooling air intakes located inside the firebox. In most applications, we allow an air space between the outside of the enclosure and the firebox opening. The Z-Door is a sleek, full-framed, tarnish-free anodized aluminum enclosure.

Can't choose the dino... sad!
I have a beagle/jack russel mix. Needless to say, he is very high-energy and does best when given a job to do that involves chewing. He LOVES his Novabone and Nylabone- but tears thru the larger sizes in a single afternoon- so when I saw this I was very happy, because it is an unusual shape and durable! Amazon's iphone app let you scan in an item and find it cheaper on Amazon- so instead of the higher pet shop price, I scored a savings deal on Amazon! Nice! My big, fat, sad complaint is that you cannot CHOOSE the dinosaur! I knew this when ordering and the stegosaurus arrived- honestly I was hoping for the T-Rex or the Brontosaurus but I guess you get what you get. Still, a beagle gnawing on a T-Rex would be pretty funny...

Great Toy for Teething and Strong Chewer
Eli is now 10 months old, a labrador retriever that proves time and time again he needs toys that he can chew, but won't fall apart. He cannot have the stuffed animal toys (no, those he'll tear apart in SECONDS, never mind minutes). Aside from the Kong and the antler, this is the only toy he can chew on that won't fall apart. Even animal bones will split in minutes. Since he was a couple of months old, he has loved this Dinosaur Chew Toy. When he was teething, I'd put it in the freezer (sometimes put peanut butter on it to keep his interest). It was not only great for teething, but also massaged his gums. Now that he's out of teething phase, he still loves to chew on it. For the money, this is worth it. It's saved the furniture and the house from being chewed on, as he focused on this toy instead. Highly recommend, especially for the price. For any strong-chewing pup or dog in particular, this toy won't shatter, split or break apart.

Cracked Tooth
Update: While I originally loved this product and so did my dogs, I feel the need to update this review. The Dura Chew Nylabones are incredibly hard, which is what makes them last so long. However, one of our dogs did crack a tooth recently from chewing on a Dura Chew. Since then, we have been very hesitant to allow any of our dogs to chew on these as other reviews also state that dogs have cracked teeth. We have since thrown out all of the Dura Chews that we had. We are still using the regular Nylabone products (when they aren't made in China), but once those are gone we will not buy any additional products from Nylabone. We have been buying Whimzees for our dogs for the last two years or so and they are a healthy edible alternative. They do not last as long because they are edible, but I have the peace of mind in knowing that my dogs are safe with them. Another healthy alternative would be antlers, which we also give to our dogs and they usually last a long time. Original review: Another great Nylabone product. I love that dogs can chew on Nylabone products and they can't pull off pieces like products from other brands (Hartz for example). The Dura Chews are especially great for our hard chewers and they last forever! I love all of the dimples on their chews too, they're great for keeping our dogs' teeth clean. The vet is always impressed when they check their teeth.

Excellent for heavy chewers!
Flavor Name: Beef, Size: Mini
My dog is between 1-2 years old, and is a heavy chewer. So far the Better Bone is lasting very well! He still is chewing away at it! Excellent quality, and I appreciate that there’s no plastic that my dog is consuming.

By far ... the SAFEST and most DURABLE bone for dogs that are hardy chewers!
Flavor Name: Beef, Size: Large
After searching high and low for a NON-TOXIC, DURABLE and truly SAFE dog bone, I finally found the large, beef-flavored, HARD version of the BetterBone for my year-plus-old rescue (Carolina Dog). 1 - it's made of all NATURAL food-grade materials (cellulose from plant cell walls) ... which means no nylon, no GMOs, and no other artificials materials so it doesn't event stain your flooring. My girl loves the tasty beef flavor. 2 - the wishbone DESIGN is genius because it gives her 3 ends to choose from (nubs v raised edges v smooth) and ample ways to stabilize it on the floor with her paws. 3 - it is uber DURABLE in standing up to the hardiest of chewers (my girl gnaws on hers daily and sometimes even multiple 10-minute sessions per day). It works great to clean and reduce tartar on her teeth. The biggest surprise was that it took 6 months for her to gnaw it down to a size that was no longer safe for her (i.e. a potential choking hazard), so I donated it to a lady with tiny dogs at the dog park. At $20 per large bone, it's a good value. 4 - and most importantly, ... it is super SAFE. It degrades in tiny little pieces that could not possibly cause a choking hazard, and being all natural (i.e. no nylon - which most bones do have), there is no worry if she does ingest some of the particles. They vacuum up with ease. The large bone weighs in at just over 12 ounces so it's kinda' heavy (9.25" long x 5" wide x 2" thick), but my 56 lb girl has no problem picking it up in her mouth before she hops up on the couch with me or into her bed. Thank you BetterBone for making a superior product that is healthy, safe and fun for my pup!
