Latham 7000MS High Shade Mesh 20' x 44' Rectangle Pool Safety Cover
Maximum shade, minimum spring cleanup.
The Latham 7000MS High Shade Mesh Safety Cover for 20' x 44' Rectangle pools (SKU PST-CSGMP20440, MPN CSGMP20440) is the ultra-fine weave step up from standard mesh: it blocks 99% of sunlight and filters dirt particles down to 40 microns while rain and snowmelt drain straight through. Tensioned on low profile double springs and ultrasonic-hardened brass deck anchors, it forms a taut barrier over the water for the whole off-season instead of a tarp anything can slip under. Latham backs the 7000MS with a 20-year limited warranty, 5 years full and 15 years prorated.
Ultra-Fine Weave, 99% Shade
Algae needs light, and the 7000MS starves it of almost all of it. The patented ultra-fine weave blocks 99% of sunlight and screens fine dirt down to 40 microns, so what falls on the cover stays on the cover instead of settling on your plaster. Owners who fight green water every April notice the difference the first time they pull this one off. Standard mesh lets roughly nine times more light through.
Drains Itself, No Pump Needed
Rain and melting snow pass straight through the weave and back into the pool, so there is never a pond on top to pump off, freeze solid, or sag into the water where a child or pet could reach it. You skip the cover pump, the extension cord, and the January trip outside to reset it. At 7 oz the fabric is still light enough that fall install and spring removal stay a two-person job.
Commercial-Grade Hardware
Every 7000MS ships with Latham's low profile double springs with D-rings and vinyl sleeves, so the cover lies flat and pulls tight whatever the pool shape. Springs tension against ultrasonic-hardened brass deck anchors that are corrosion resistant and retract flush into the deck when the cover is off. A dual strapping system is sewn to both sides of the cover with a triple-stitched seam and bar and box tack reinforcement at every perimeter strap.
Who It's For
Homes With Kids & Pets
An anchored, tensioned barrier over the water all winter, tested to meet or exceed ASTM F1346, instead of a floating tarp with water bags around the edge.
High-Sun Climates
Where a standard mesh cover still lets enough light through to green the water, the 99% shade weave keeps the pool dark from close to open.
Tree-Heavy Backyards
The fine weave screens the silt and grit that ordinary mesh passes through, so leaf litter and windblown dirt stay on top rather than in your filter.
Snow and Rain Country
Snowmelt and rain drain through instead of ponding on top, so the cover stays flat and tight through repeated freeze and thaw cycles.
Why PST Customers Pick This
Real Safety Barrier
Spring tension and brass deck anchors hold the cover taut over the water, helping keep children and pets out. Water-bag winter tarps cannot do that.
Blocks 99% of Sunlight
The patented ultra-fine weave shades the water almost completely through the off-season, which is the single biggest lever on spring algae.
No Standing Water
Rain and snowmelt drain straight through the mesh, so you never buy, power, or babysit a cover pump.
40 Micron Filtration
Fine dirt and silt are screened out at the surface instead of washing into the pool, so opening day means less vacuuming and less filter cleaning.
Triple-Stitched Straps
Dual straps are sewn to both sides of the cover with triple-stitched seams, plus bar and box tack reinforcement on every perimeter strap.
Kem-Kap Access
Latham's Kem-Kap gives you convenient service access through the cover, and interlocked, double overlapped seams keep the weight on the webbing.
Safety Notice
A safety cover only performs as a barrier when every anchor is set in sound concrete or decking and every spring is tensioned to Latham's instructions. This cover is tested to meet or exceed ASTM F1346; keep it fully anchored whenever the pool is unattended, recheck tension through the winter, and do not allow anyone to walk on it.

Frequently Asked Questions
What is the difference between the 5000M, the 7000MS and the 9000MX?
The 5000M is Latham's standard micro weave mesh: 5 oz fabric, 91% sun block, 15-year warranty. The 7000MS on this page is the high shade step up, an ultra-fine 7 oz weave that blocks 99% of sunlight, filters to 40 microns, and carries a 20-year warranty. The 9000MX is the reinforced heavy duty mesh with a 25-year warranty. All three anchor and tension the same way.
How is this different from the solid HD 1000V cover?
The 7000MS is mesh, so water drains through it and you never need a pump. The HD 1000V is 12 oz solid vinyl that blocks 100% of light and all debris, and it moves water off the surface through Latham's Invis-A-Drain panel. Mesh is lighter and lower maintenance; solid keeps every speck of dirt out. Most owners in snow country pick mesh.
What size cover should I order?
Order by your pool's water dimensions. A 20' x 44' cover is built for a 20' x 44' pool, and the finished fabric is cut larger so it overlaps the deck and reaches the anchors on all sides. If your pool has a step section, order the matching step shape so the cover follows your outline instead of bridging over the steps.
Can I install this myself?
Most owners do. The first install means laying the cover out, drilling anchor sockets in the concrete deck with a hammer drill and masonry bit, setting the brass anchors, then stretching each spring on with the included installation tool. Wood deck and raised wall anchor options are available. After the first season, install and removal are a quick two-person job.
Do I need a cover pump with this cover?
No. Rain and snowmelt drain straight through the mesh into the pool, so water never accumulates on top. That is the main reason owners choose mesh over a solid cover.
Will the 99% shade actually stop spring algae?
It removes the light algae needs, which is most of the battle. Pair it with proper winterization chemistry and you will typically open to clear water instead of a green pool. The 7000MS is the cover to choose if your standard mesh has been letting the pool turn over the winter.
What colors does the 7000MS come in?
Latham manufactures the 7000MS in green, blue, grey and tan. This listing is the color shown in the title, which is what we stock for fast shipment.

Let customers speak for us
The bulb was lost in transit and PST reached out proactively to ask if I wanted a replacement shipped out!
part was an exact fit for my old spa, price was great thanks
Fast shipping and great customer support. I appreciate all of the help in getting my spa up and working.
The cord worked perfectly when I upgraded my older Balboa spa and pump.
I had a leak in which water was leaking out to the waste line. I could hear the water trickling in the waste line. The spider gasket in this kit resolved the issue.
Shipping and delivery were quick. Would definitely order again from PST.
Fit perfectly and works great.
Awesome item. I can control my spa from my phone!! Love it. Item was shipoed out and delivered so fast. Hooking it up was a breeze.
The support staff to make the orders were outstanding; even though I made a quantity error. And the timeliness of all the repair parts I needed to get the OLD Tiger Shark running as good as new was wonderful. My pool is crystal clear.
Fit perfectly on our bubbler lightv
The only place I could find with the part I needed. Delivery was fast and the price was great. Best pool supply store on the web.
Part was easy to find and arrived a couple of days earlier than originally scheduled.
The ceramic spindle in the center of the original impellor broke. Replacement with this part was super easy and pump performs like new.
