2 year limited warrantyThe Rhino Shelter 12X24 Extended Instant Garage by MDM Products, the country's leading maker of vinyl structures of all sizes, is perfect for storing large vehicles, motorcyles, boats, lawn equipment, or just about anything else. With its ease of assembly and high-quality construction, it is a tremendous value for a shed of this size.

Rhino Shelter steel tubingRhino Shelter vinyl structures are the strongest on the market as they use high quality multi-layer fabric and heavy-duty galvanized structural steel tubing. Other manufacturers skimp on these critical components and consequently their structures fail at the slight hint of inclimate weather. MDM Products is based in Connecticut, and so all of its structures are designed to withstand the severe weather the East Coast is prone to.

Shipping included for the contiguous United StatesLarge roll-up end panels allow for easy access from both sides and complete ventilation. The shed is low maintenance and won't fade, mildew, or rot as a wood structure may over time. Simply an occasional wash with a garden hose will keep it looking new over time.

Rhino Shelter logoDesigned for easy assembly with common household tools, the Rhino Shelter 12X24 Extended Instant Garage can be put together in just a few hours or less depending on how much help you have. Available in green or grey, this shed is sure to provide your family plenty of use for years to come.

Optional Accessories

rhino shelter cable hook anchorAnchors (Cable Hook) - Rhino Shelter portable structures come with very strong cable hook anchors that attach to the bottom cross rail of the pipe frame with 1-5/8" or 2-3/8" U-bolts depending on the size of the structure. Enough anchors are included for just about every application. Some customers prefer to have even more anchoring, and so extra individual cable hook anchors and U-bolts are available.

Anchors (Ground Auger) - Some customers prefer auger-style anchors, which work great in dirt and are reusable and easy to install. Six large 32 inch auger anchors are available that have a pull-out strength of 1200 pounds, the same as the included cable hook anchors. Six small 16 inch auger anchors are also available that have a pull-out strength of 800 pounds.

Extended Warranty - Rhino Shelter portable structures all come with an industry-leading 2 year limited warranty.  The extended warranty is provided by the manufacturer directly and can extend this warranty to 3 years or 5 years.

rhino shelter floor kitFloor Kit - The Rhino Shelter Floor Kit acts as a vapor barrier for your structure as it block moisture and condensation from the ground. It also keeps weeds out, and is useful when having a completely enclosed spaceis needed. The floor kit will fit structures up to 12' wide x 24' long, and can be easily cut to fit any size.

rhino shelter joiner kitJoiner Kit - The joiner kit from Rhino Shelter is used to connect two structures together into one large unit. The weather strip is available for units of all widths and seals the combined structure from rain, snow, and wind. It is available in your choice of three colors and is made of a 36" wide, 22mm thick fabric that has a heavy 10 ounce per square meter weight. The joiner kit provides a cost-effective way to greatly increase your storage space.

Liftgate For Delivery - The customer is required to have at least one person present to sign for the delivery and help unload the pallet from the truck. When your Rhino Shelter portable structure arrives from the shipper, the liftgate is a crane-type device that takes the giant pallet off the truck and places it in your driveway.

Without the liftgate, the customer will have to remove the box or boxes from the truck manually. This is usually done by opening the shrink wrap and moving each piece to its destination in your garage or backyard. This procedure usually only takes 15 or 20 minutes, and each piece may weigh anywhere from 40 to 80 pounds or less. The driver is not obligated to help unload the delivery, though we have not found this to ever be a problem.

Ideally two people will be present to accept delivery so that everything is unloaded quickly and moved safely, and the customer will have a hand truck for easier mobility. The liftgate is recommended for the very largest deliveries but is not necessary for most of the smaller structures.

rhino shelter roll-up door kitRoll-Up Door Kit - The Rhino Shelter Roll-Up Door Kit makes opening and closing your structure's door a cinch. A easy to install pulley system makes opening the door as simple as opening window blinds. Two kits are suggested, one for each end of the structure. All the necessary ropes and pulleys are included with each kit.

rhino shelter vented end panelVented End Panels - Rhino Shelters can come with vents already sewn in the end panels above the door so that no extra installation is needed. These vents add air circulation to prevent excess heat or condensation from building up. The vents include a fabric cover that easily closes with velcro to seal the vent when not in use. They are available in whatever color you choose so that they match the rest of your structure and two come in each kit, one for each end panel.

rhino shelter ventilation kit
Ventilation Kit - This kit adds two 12 inch square, plastic injection molded vents to your Rhino Shelter portable structure. Sometimes in extreme weather conditions, extra ventilation is needed to reduce the internal temperature or help remove excess humidity with increased air circulation. The vents are designed for easy installation.

Benefits of Rhino Shelter structures

rhino shelter 1 5/8 inch galvanized pipeHeavy Duty Galvanized Steel Frame - Rhino Shelter structures up to 12' x 24' use 1-5/8" diameter tubing, while the largest structures bigger than 12' x 28' and above use 2-3/8" diameter tubing. Only the Party Tents, Party Canopies, and Steel Carports use a different frame system.

The double-dipped manufacturing process gives a triple-layered coating to provide added strength and protection against the elements and ensure that the frame is completely corrosion-free. 

The inital flat strip steel is cold-formed and induction welded and then is subjected to two coating baths. The bonds zinc to the hot tubing and then a conversion coating above. The final protective coating is a clear organic polymer that gives the surfact its smoothness and brightness. These coatings will not flake off during construction or dull with age, and the frame construction and design ensures that your structure will be rigid and durable for years to come.

rhino shelter heavy duty fabricIndustrial Grade Fabric - The strong vinyl covers used in Rhino Shelter structures have three layers in a triple stack weave for significant durability. The seams are heat-bonded to make everything fits perfectly over the frame.

The unique rip-stop polyethylene used prevents any small tears that occur from expanding. The white underside allows maximum light reflection inside your structure for added brightness. 

The cover is UV-treated on both sides with a 10% chemical treatment, and the inner black scrim layer, unique to Rhino Shelter, blocks 100% of sunlight and UV rays from penetrating through the material. This allows covers to last an average of 7-10 years, depending on the level of sun exposure, while cooling the temperature inside. The effective lifespan of the cover is considerably longer than the covers used by competitors, and replacement covers are available at an affordable price.

rhino shelter pre-drilled bolt-together framePre-Drilled Bolt-Together Frame - No cutting or drilling is needed during assembly, and power tools are not even needed.

rhino shelter heavy duty anchorsCable Hook Anchors - Rhino Shelters use 3 feet long anchors with rust-proof stainless steel anchors. The anchors easily go into the ground without digging with the drive rod that fits in the head of each anchor. Each set of anchors has a pull-out strength of 1200 pounds, four times higher than auger anchors typically used by other manufacturers. Rhino Shelter party tents are anchored by ground stakes while the metal carports use stainless steel pins.

rhino shelter ratchet strapsRatchet Straps - The heavy duty straps are unique to Rhino Shelter structures and allow the cover to go over the frame with the tighest fit possible. The reinforced webbed strap material and turnbuckle design will prevent any ripping and helps create a wrinkle-free look quickly.

The straps allow the cover to fit more squarely on the frame as well, making adjustment of the fabric on the bottom cross rail easier, and unlike rope, they will not stretch or allow the cover to get loose over time.

rhino shelters are designed to withstand winter weatherDesigned To Withstand Winter Weather - Rhino Shelter structures are able to withstand winter storms in heavy snow areas. The roof is typically sloped or rounded and the covers are smooth to help snow slide off. The structures do not have engineered official snow load capacities as they are portable. In case snow accumulates, simply tap on the building's ceiling from the inside to dislodge it if it is safe to do so.
