Mier a One-Stop Shop for Enclosures
The addition of non-metallic enclosures to a large inventory of metal enclosures makes fabricator Mier Products a one-stop shop for enclosures.
As a longtime manufacturer of painted metal enclosures for the security, fire and electronic industries, we have heard a continuing call for non-metallic boxes. So it is a natural move for Mier to introduce a high-quality and versatile line of polycarbonate enclosures in a mirad of sizes and loaded with numerous features.
The appeal of polycarbonate enclosures is far-reaching because of their superior performance in so many different environments. Three important considerations for using polycarbonate boxes include high impact strength, their non-corrosive (no rust) abilities and they are non-conductive, eliminating a shock hazard.
The design of these enclosures makes them ideal for use in the harshest of environments . . . such as oil refineries, electrical construction, irrigation systems, chemical processing facilities, water treatment plants, car wash operations, sewage plants, utility fields, instrumentation, machine building and HVAC . . . anywhere protection from rugged environments is demanded.
In the case of wireless products, non-metallic enclosures are perfect for the application because antennae or transmitters may be mounted in the enclosure without hindering the reception or transmission of radio wave signals.
These Mier enclosures have passed stringent Underwriters Laboratories (UL) testing and are listed under UL-50/c-UL. They also carry NEMA ratings, with the L Series carrying a 6/6P Marine use, which means these enclosures may be submersed.
The L Series:
There are two series of products, each with well thought-out capabilities. The L Series, a totally molded enclosure, features a latching/padlock provision, which snaps shut securely. This action draws the molded-in gasket of the door tightly against the chassis when it is snapped shut.
There are several appealing features of the L Series for OEM use, including size. Relatively small, the largest being 9” tall, 8” wide and only 2” deep, this series is ideal for small component mounting. It is finished in a handsome light gray gloss.
The hinged easy-to-remove door is ideal for OEM applications where hand assembling of components allows access to the interior of the box. Other features ideal for OEM use are the multiple bosses, conveniently spaced around the perimeter of the box, and permit mounting of components, circuit boards, back panels, or DIN rails . . . simply by using #10 self-tapping screws. Other features include integrated mounting flanges on top and bottom of the enclosure so that it may be rotated to permit the door to open left or right. Clear doors are also available.
Other attractive features are back panels, made of steel or PVC, and the ability to have those punched to a hole pattern as desired in minimum quantities of 25 pieces. Blank panels may be purchased in any quantity. Pole mounting kits are also available.
Another appealing factor is cost, made so by the all-molded process and absence of any component assembly, such as hinges or latches.
The availability of an array of sizes is one of the features of the SL Series. From the smallest enclosure of 8” tall, 6” wide and 4” deep to the largest at 18” x 16” x 10” there is an enclosure sized to fit most needs.
With plenty of appeal to OEMs because of the size and features versatility, the SL Series also fits the needs for a variety of one-of-a-kind installations. Easy to machine or punch, this series has stainless steel latches and different mounting methods, plus multiple bosses for mounting circuit boards, back panels, components and DIN rails.
A unique feature of the SL Series is a Back Panel Suspension system. This patented system allows back panels to be suspended at any height within the enclosure, and allows stacking of the panels. This is accomplished by mounting pads that slide on T-shaped rails molded into the enclosure. The mounting pads are held in place by a set screw, which can be adjusted with the back panel in place as the pads move on the T-rail. The kit comes complete with everything needed.
As with all Mier non-metallic enclosures, a clear door is available for those instances when it is desirable for viewing the interior. Back panels in steel or PVC and Pole Mounting Kits are also available.

Listening to Customers is the Key to Our R&D
Perhaps the most important part of Research and Development of new products is listening . . . the discovery of the product idea. In our case, we have currently developed two new products, thanks to our customers who generated ideas! The results are a much-needed shelf accessory to go along with our DVR and CPU Lockboxes; and the addition of three new outdoor/indoor fan-cooled enclosures to our Temperature Controlled Enclosures line.
Actually, these customer product suggestions weren’t very subtle because in both cases we had many customers who thought the products were “naturals” for us and complemented products in our standard enclosure lines.
The results are a much-needed shelf accessory to go along with our DVR and CPU Lockboxes; and the addition of three new fan-cooled outdoor/indoor enclosures to our Temperature Controlled Enclosure line.
Our New DVR/CPU Lockbox Shelf:
The BW-215 Wall-Mount Shelf is truly a natural to accompany five of our seven models of lockboxes. Finding the ideal place to install DVRs in a lockbox is not always an easy task, and the shelf is a real solution to making the job easier. The shelf is designed to mount onto a single wall stud, which makes finding the right location a bit easier. They are made of hefty 14 and 16 gauge steel and powder-coated black to match the lockboxes. They are simple to hang onto the wall, and fasteners are provided to do the job. Better yet, the shelf is designed to fit our lockboxes. Once the shelf is fastened to the wall, we’ve matched holes in the shelf with mounting holes in the bottom of our lockboxes so the DVR/CPU Lockbox is securely attached to the shelf. Again, all fasteners are provided.
Our New Fan-Cooled Enclosures:
We have added fan-cooled cabinets to our line of Temperature Controlled Enclosures, also due to customer input. This line of enclosures has always been NEMA 4 and included air-conditioning and heating units to protect the fire-panels, DVRs, or other electronic equipment mounted within. However, installers were stating that in some cases this amount of temperature control was overkill. Therefore, these new NEMA 3R Fan-Cooled units were strictly designed for those instances when air-conditioning or heating is not needed, but a constant exchange of ambient air and air inside the enclosure is sufficient. The fan-cooled units are not a substitute for the demands of enclosures where air-conditioning and heating are necessary or where internal components need to be protected from moisture. However, there are many interior and outdoor applications where these units are cost-effective. The enclosures come in three basic models with differing options, but all are designed with the capabilities of meeting NEMA 3R standards...which means they are for either indoor or outdoor use and provide a degree of protection from incidental contact with the enclosed equipment and against falling dirt, rain, sleet, snow, and windblown dust, and the external formation of ice on the enclosure.
Important features of these units include a continuous-duty fan, which exchanges the
These new Fan-Cooled Enclosures also come with shrouds, intended to protect the air
Both additions to our product line are the result of listening to you...our customer. Thanks for the help, and if you have other product ideas, please call or email. You have our ear!
