Loop-Loc’s Ultra-Loc III: The Strongest Solid Safety Cover on the Market

Intro

When it comes to pool safety covers, strength, reliability, and ease of use are non-negotiable—especially for homeowners who want top-tier protection without the bulk. Enter the Ultra-Loc III pool cover, Loop-Loc’s most advanced solid cover to date. Built with patented technology and unmatched durability, Ultra-Loc III delivers the highest level of safety in a lightweight, easy-to-handle design. At Big Becks Pools and Pavers, we proudly install this cover for families who refuse to compromise on quality. If you’re looking for the strongest pool safety cover on the market, this is where innovation and performance meet.

What Is Ultra-Loc III?

Ultra-Loc III is the flagship solid safety pool cover from Loop-Loc, designed to provide complete protection from debris, sunlight, and unauthorized access—all while maintaining a sleek, streamlined appearance. Unlike traditional solid covers that are heavy and difficult to manage, Ultra-Loc III is constructed from a proprietary vinyl-laminated polyester fabric that is incredibly strong yet surprisingly lightweight.

Available with either a built-in mesh drain panel or a fully solid configuration with an automatic cover pump, Ultra-Loc III gives you flexibility while delivering the premium protection you expect from Loop-Loc. Whether you’re winterizing your pool or preparing for storm season, Ultra-Loc III ensures your pool is sealed tight and secure.

Strength Without the Weight

The hallmark of the Ultra-Loc III pool cover is its unmatched strength-to-weight ratio. The solid material is nearly 33% lighter than standard vinyl covers, making it easier to handle during installation and removal—without sacrificing toughness.

In fact, Loop-Loc’s Ultra-Loc III has been independently tested and proven to exceed ASTM F1346-91 safety standards, qualifying it as a true safety cover. Its heavy-duty reinforced webbing and triple-stitched seams ensure it stands up to intense snow loads, high winds, and accidental impacts. This makes it a leading choice in any solid safety pool cover comparison.

Total Sunlight Block for Maximum Protection

One of the biggest benefits of choosing a solid safety cover like Ultra-Loc III is complete sunlight blockage. While mesh covers allow for drainage and breathability, solid covers like this one prevent sunlight from reaching the water—significantly reducing the chance of algae growth and chemical imbalance during the off-season.

This means cleaner water, easier openings in spring, and less money spent on shock treatments and rebalancing. With Ultra-Loc III, your pool stays sealed from the elements, minimizing chemical use and protecting your liner and finish from UV degradation.

Drainage or Pump: Choose Your Fit

Ultra-Loc III is available in two configurations:

• • With Drain Panels – For those who want a balance between drainage and debris protection, the mesh panels allow water to pass through while blocking dirt and sunlight.

• • With Automatic Pump – For a fully solid experience, this version includes an automatic submersible pump that activates when water collects on the cover, keeping the surface dry and clean.

Both options are designed with convenience and long-term performance in mind. Your Big Becks installer can help you decide which configuration best suits your climate, yard conditions, and maintenance preferences.

Easy Handling and Long-Term Durability

Traditional solid covers are notoriously difficult to move—but not Ultra-Loc III. Thanks to its lighter construction and flexible fabric, the cover folds easily and installs quickly, reducing strain on homeowners and installers alike.

Despite its ease of handling, Ultra-Loc III is built for long-term use. It resists mildew, UV rays, chemicals, and temperature extremes. Its heavy-duty construction is backed by Loop-Loc’s industry-leading 15-year prorated warranty, giving you the confidence that your cover will perform season after season.

Frequently Asked Questions: Loop-Loc Ultra-Loc III

What makes the Ultra-Loc III “stronger” than other solid covers? While most solid covers are made of standard heavy vinyl, the Ultra-Loc III uses a proprietary vinyl-laminated polyester fabric reinforced with a “rip-stop” scrim. This design allows it to be 33% lighter than traditional solid covers while maintaining superior tensile strength. In 2026, it remains the gold standard for handling massive snow loads on Long Island, having been independently tested to exceed ASTM F1346-91 safety standards for supporting weight in emergency situations.

Does the Ultra-Loc III really prevent all algae growth? Yes. Unlike mesh covers that allow a small percentage of UV light and fine silt to pass through, the Ultra-Loc III provides 100% sunlight blockage. This is a game-changer for 2026 spring openings; by cutting off the photosynthesis process entirely, your pool water stays as clear as the day you closed it. This significantly reduces the need for expensive “shock” treatments and heavy chemical rebalancing when you open your pool.

Should I choose the “Mesh Drain Panel” or the “Automatic Pump” version? The choice depends on your maintenance style. The Mesh Drain Panel version is “set-and-forget”—rainwater and snowmelt filter through a small, fine mesh panel into the pool, eliminating standing water on top. The Automatic Pump version is for those who want a 100% solid barrier (preventing even the smallest amount of silt or “acid rain” from entering the water). If you choose the pump version, you must ensure it remains plugged in and functional throughout the winter to prevent water from weighing down the cover.

What are the specific maintenance requirements to keep my warranty valid? To maintain Loop-Loc’s 15-year pro-rated warranty, there are three critical requirements:

• Water Level: You must keep the pool water level between 12” and 16” below the top of the pool. If the water level drops lower, the cover loses its “trampoline” support and puts excessive stress on the hardware.

• Tension: Springs should remain compressed to approximately 60% (about 2 1/2″ apart) to ensure the cover stays “drum-tight.“

• Anchor Care: In the spring, you should flush out all brass anchor casings with a hose to remove dirt and salt, then apply a light spray of silicone to ensure they continue to operate smoothly.

Is the Ultra-Loc III difficult for one person to install? Thanks to its lightweight design, the Ultra-Loc III is much easier to manage than older solid vinyl covers. While a 20′ x 40′ solid cover used to weigh over 100 lbs, the Ultra-Loc III is significantly lighter, making it manageable for a two-person team to pull across the pool. Once the first eight anchors are set using the installation rod, the rest of the straps can be snapped into place with minimal physical strain.

How does the 2026 CAD-design process improve the fit? At Big Becks, we use Computer-Aided Design (CAD) to measure your pool’s exact perimeter, including any custom features like waterfalls, raised spas, or non-standard steps. Loop-Loc uses these digital coordinates to manufacture your Ultra-Loc III cover with a “Perfect Fit” guarantee. This ensures there are no gaps or bunches in the material, which is vital for both the safety of the cover and the overall aesthetic of your backyard.
