ASSE 1060 compliant aluminum
Heated & unheated models
A backflow preventer left exposed outdoors faces two constant threats: freezing temperatures that can crack the assembly and split internal components, and tampering or theft of the brass and bronze parts. A Safe-T-Cover backflow enclosure solves both. These aluminum backflow preventer covers shield the assembly from the weather, lock out unauthorized access, and — in heated models — hold the interior above freezing through the coldest months so your water stays on and your assembly stays compliant.
Safe-T-Cover is the most widely specified aluminum enclosure line in the country, and every model Eastgate Supply stocks is ASSE 1060 compliant — the national standard for backflow enclosure performance covering insulation, drainage, structural strength, and security. Whether you're protecting a small residential RPZ, a double-check assembly at a commercial site, or a large municipal installation, there's a Safe-T-Cover series sized for the job.

Why Safe-T-Cover
Built to Protect Your Assembly Year-Round
Aluminum construction and an ASSE 1060 design give Safe-T-Cover enclosures an advantage over fiberglass and site-built covers.
Freeze Protection
Insulated, heated models hold the interior above freezing so RPZ and double-check assemblies keep working through winter without splitting.
Vandal & Theft Resistance
Locking aluminum panels protect the brass and bronze in your assembly from tampering, theft, and accidental damage.
ASSE 1060 Compliant
Every model meets the national standard for insulation, drainage, structural load, and security — so your install passes inspection.
Corrosion-Resistant Aluminum
Aluminum won't rust like steel or crack and fade like fiberglass, giving you a longer service life with less maintenance.
Easy Access for Testing
Removable and hinged panels give certified testers clear access to test cocks and shutoffs for the annual backflow test.
Sized for Every Assembly
Seven series cover everything from small residential preventers to large municipal assemblies with multiple line sizes.
Choosing a Model
Heated vs. Unheated Backflow Enclosures
The right choice comes down to your climate and whether the line needs to stay in service through freezing weather.
| Unheated Enclosure | Heated Enclosure | |
|---|---|---|
| Best for | Mild climates or lines drained for winter | Freezing climates where the line stays charged |
| Freeze protection | Insulation only | Insulation plus a thermostatically controlled heater |
| Power required | No | Yes — a dedicated circuit at the install site |
| Protects against vandalism | Yes | Yes |
| ASSE 1060 class | Meets the non-freeze classes | Meets the freeze-protection class |
If your backflow preventer is on a line that has to keep flowing in winter — fire protection, domestic supply, or irrigation that isn't winterized — choose a heated Safe-T-Cover model. If you're in a mild climate or the line is shut down and drained before the first freeze, an unheated enclosure gives you weather and vandal protection at a lower cost.
Sizing Guide
How to Size a Safe-T-Cover Enclosure
Picking the right enclosure starts with the assembly inside it, not the enclosure itself. Gather these details before you order:
- Assembly make and model — different manufacturers build the same line size to different overall dimensions.
- Overall length, width, and height — measure the installed assembly including the relief valve and any clearance the manufacturer requires.
- Pipe size and center-line height — the diameter of the line and how high it sits above the slab determine the inlet/outlet openings.
- Test and shutoff access — leave room for a tester to reach the test cocks and turn the shutoff handles.
With those numbers, compare interior clearances in the backflow enclosures master table, or let the size finder match your assembly to the Safe-T-Cover models that fit. When in doubt, size up — an enclosure that's slightly large is far easier to work in than one that's too tight for the annual test.
Questions
Safe-T-Cover FAQ
What is a Safe-T-Cover backflow enclosure?
It's an aluminum, ASSE 1060 compliant cover that goes over an outdoor backflow preventer to protect it from freezing temperatures, weather, and vandalism. Heated models keep the interior above freezing so the assembly stays in service through winter.
Do I need a heated or unheated enclosure?
Choose a heated enclosure if the line stays charged through freezing weather. Choose unheated if you're in a mild climate or the line is drained for winter. Heated models need a dedicated power circuit at the install site.
How do I know which size to order?
Measure your installed assembly's overall length, width, and height (including the relief valve), and note the make, model, and pipe size. Then match those numbers against the master table or use the size finder. If you're between sizes, size up for easier testing access.
Are Safe-T-Cover enclosures ASSE 1060 compliant?
Yes. Every Safe-T-Cover model meets the ASSE 1060 standard, which covers insulation, drainage, structural strength, and security. Most local codes require ASSE 1060 certification for backflow enclosures.
Why aluminum instead of fiberglass?
Aluminum resists corrosion, won't crack or fade in UV like fiberglass can, and stands up to impact and tampering. It generally delivers a longer service life with less maintenance.
Where do these ship from and what does shipping cost?
Eastgate Supply ships Safe-T-Cover enclosures nationwide with free shipping on every order. Some larger models are built to order with a short lead time — call us if you need a delivery date confirmed.
