Open-front display cases are fantastic for selling. Customers can see your drinks, dairy, salads and grab-and-go items and pick them up without opening a door. But when the store closes, that open front becomes a problem. Cold air escapes, the compressor works harder and the product sits exposed. A security cover solves all of this in one simple step.

This guide is based on the topic of the video "How To Install The Fabric Security Cover" from Turbo Air. We explain what a fabric security cover is, why it is worth installing, how to prepare, the general installation process, common mistakes and how to look after the cover over time.

Important: This article gives general guidance. Always follow the instruction sheet that comes with your exact cover and merchandiser model, and contact Turbo Air or a qualified technician if you are unsure about any step.

What Is a Fabric Security Cover?

A fabric security cover, often called a night cover, is a flexible cover that closes off the open front of a refrigerated merchandiser when the store is closed. Turbo Air offers locking security covers for its TOM-series open merchandisers, and the fabric versions are typically supplied with trim and are described as field-installed, meaning you can fit them on site after the unit is in place.

Covers are usually sized to match specific models. Turbo Air lists separate cover models for different merchandiser widths and finishes, so a cover made for a 36-inch unit will not suit a 60-inch one. Matching the cover to your exact model is the first rule of a successful install.

Why Install a Security Cover on an Open Merchandiser?

It Saves Energy

Air curtains keep cold air inside an open case during the day, but at night, with no one shopping, a physical barrier does a better job. Covering the opening reduces cold air loss, so the system does not have to work as hard to hold temperature.

It Protects Your Product

Covered products are shielded from dust, debris and accidental contact after hours. Temperature also stays more stable, which supports food safety.

It Adds Security

The "locking" part matters. A locking cover discourages tampering and helps protect stock overnight.

It Keeps Your Store Tidy

A neat fabric cover gives the unit a finished look when the lights go down, and it hides cluttered shelves during cleaning or restocking.

It Reduces Wear and Tear

Less strain on the refrigeration system can mean fewer breakdowns and a longer service life for your equipment.

Fabric vs. Hard vs. Stainless Security Covers

Turbo Air offers more than one type of security cover, and the best choice depends on your store.

• Fabric covers: lightweight, flexible and easy to handle. A good fit for stores that want quick daily use and a simple look.
• Hard plastic covers: a more rigid option that offers extra protection from impact. See our guide on how to install the hard security cover.
• Stainless steel covers: the most robust option, suited to higher-traffic or higher-risk locations. See how to install the stainless security cover.

If you are not sure which suits your business, compare how often the cover will be used, how much security you need and how it fits your store's look.

Before You Start: Preparation Checklist

A careful setup avoids most problems. Work through the list below before touching any hardware.

Confirm Your Model and Cover Match

Check the nameplate on your merchandiser and compare it to the cover's model number and size. Look at width, trim color and mounting type.

Unbox and Inspect Everything

If the merchandiser is brand new, start with our guide on how to unbox a Turbo Air open merchandiser. Then unpack the cover carefully and check for tears, bent trim, missing hardware or damaged locks.

Clear the Area

Remove stock from the front of the unit, or at least from the area where you will be working. Move displays and floor mats that could trip you.

Gather Tools and Help

Exact tools depend on the model, but you will commonly need:

• A screwdriver set
• A drill or driver, if the instructions call for one
• A measuring tape and level
• Clean gloves or a soft cloth to protect the fabric
• A step stool or ladder
• The manufacturer's instruction sheet

For wider covers, ask a second person to help hold the cover while you fasten it.

Safety Tips

• Turn off or unplug the unit if you will be working near fans, lights or wiring.
• Use a stable step stool or ladder and never overreach.
• Handle the fabric gently. Snagging or tearing the material at this stage can ruin the cover.
• Do not force parts together. If something does not align, stop and check the instructions.
• Keep fingers clear of moving parts and edges when fitting hardware.

Step-by-Step: How to Install a Fabric Security Cover

The details differ by model, so use this as a general framework and defer to your manufacturer's instructions.

Step 1: Lay Out All Parts

Place the cover, trim pieces, brackets, screws and lock components on a clean surface. Compare them with the parts list in your instructions so nothing is missing.

Step 2: Mark and Measure the Mounting Positions

Use your measuring tape and level to identify where the mounting hardware will sit along the top or sides of the opening. Mark positions lightly so the cover will hang straight. Measuring twice avoids drilling extra holes.

Step 3: Install the Mounting Brackets or Trim

Attach the brackets or trim to the unit as directed. Fasten them securely but do not overtighten, which can strip the screw holes or deform the metal.

Step 4: Attach the Fabric Cover

Hang or secure the fabric to its mounting points, keeping it smooth and evenly spaced. Check that the material is not twisted or bunched. Work from one side to the other so the tension stays even.

Step 5: Fit the Locking Mechanism

Install the lock or latch according to the instructions. Test that it engages smoothly and holds the cover firmly closed. Keep any keys in a safe, known place.

Step 6: Test Opening and Closing

Open and close the cover several times. It should move easily without catching on shelves, trim or product. If it drags, check alignment before fastening everything fully.

Step 7: Final Check

Look over the finished install from the front and sides. Make sure the cover seals the opening well, the trim sits flush and there are no loose screws or tools left on the unit.

Common Mistakes to Avoid

1. Ordering the wrong cover size. Always match the model first.
2. Skipping the instruction sheet. It contains model-specific details.
3. Not measuring carefully. A crooked cover looks poor and may not seal properly.
4. Over-tightening screws. This damages brackets and fabric attachments.
5. Pulling the fabric too tight or leaving it too loose. Both cause wear and poor sealing.
6. Forgetting to test the lock. Make sure it works before you rely on it.
7. Covering a unit that is not at temperature. Only cover the case once product is cold and stable.
8. Leaving the cover on during business hours. It should only be used when the store is closed or the unit is not in use.

Daily Use Tips

• Close the cover at the end of each night once the shelves are stocked and the unit is at proper temperature.
• Remove it before opening so the air curtain can work as designed during business hours.
• Check product temperatures regularly, especially in the first week after installing a cover.
• Train staff so everyone handles the cover gently and uses the lock correctly.

Maintenance and Care

Clean the Fabric

Wipe with a soft, damp cloth and mild cleaner. Avoid harsh chemicals or abrasive scrubbing that can fade or weaken the fabric.

Inspect Regularly

Look for loose stitching, frayed edges, sagging, rust on hardware or lock problems. Fix small issues before they become bigger ones.

Care for the Unit Too

A cover works best on a well-maintained merchandiser. Keep the unit properly set up with the right shelf height, correct defrost temperature settings and working LED lighting.

Replace When Needed

If the cover is torn, stretched out or no longer seals properly, replace it. Browse our Turbo Air parts collection for genuine components, or read our guide on stocking OEM parts.
