GLI Secur-A-Pool 20' x 50' Rectangle Mesh Pool Safety Cover, Green
Blocks 93% of sun, drains itself.
The GLI Secur-A-Pool 20' x 50' Rectangle mesh pool safety cover, Green (SKU PST-202050RESAPGRN) locks your in-ground pool down for the off-season with a high weave count polypropylene mesh that gives you 93% sun shade while rain and melting snow drain straight through to the pool. Nothing ponds on the surface, so there is no cover pump to power through a freeze, and dirt and leaves stay on top instead of sinking to the floor. Your cover ships complete with brass deck anchors, stainless steel springs, the installation rod, and a storage bag, backed by GLI's 15-year limited warranty with 3 years of full coverage.
Mesh That Screens Out Winter
Secur-A-Pool uses GLI's patented polypropylene mesh blend with an increased weave count, so you get 93% sun shade over the water all winter while rain and snowmelt pass right through to the pool. Standing water hazards never form on the surface, and the tight weave screens dirt, leaves, and pine debris out of the pool instead of letting it settle on the floor. You open in spring to clear water instead of a swamp, and you never buy or babysit a cover pump.
Tamper-Proof Anchoring System
Solid brass anchors sink flush into your deck and disappear once the cover comes off for swim season, so nobody trips on hardware in July. Stainless steel springs hold the cover under even tension across every strap, and the cover only releases with the included installation rod, which is what makes the system tamper-proof against curious kids. Once the anchors are drilled the first time, seasonal on and off takes minutes, not an afternoon.
Built to the ASTM Standard
Every Secur-A-Pool cover meets or exceeds the manual safety cover performance standards in ASTM F1346-91, the same standard municipal codes point to when they require a barrier over the water. Anchored and tensioned per the owner's manual, the cover holds an adult's weight and keeps children, pets, and stray animals off the pool. GLI backs it with a 15-year limited warranty that includes 3 years of full coverage.
Who It's For
Families With Kids & Pets
Anchored and tensioned correctly, the cover is a real barrier over the water that meets or exceeds ASTM F1346-91, not a floating tarp.
Wooded Backyards
The high weave count mesh keeps leaves, seed pods, and grit on top of the cover where a blower can clear it in a few minutes.
Snow Country Pools
Melting snow drains straight through, so weight never builds up on the surface and no cover pump has to survive a freeze.
Hands-Off Winterizers
If you want to close in the fall and not think about the pool again until April, mesh is the lowest maintenance safety cover you can buy.
Why PST Customers Pick This
Meets ASTM F1346-91
Built to meet or exceed the published performance standards for manual safety covers, so it satisfies barrier requirements where local code calls for one.
No Cover Pump Needed
Water and snowmelt drain through the mesh instead of pooling, so you skip the pump, the extension cord, and the mid-winter check-ups.
93% Sun Shade
Cutting 93% of sunlight starves algae through the off-season, which means less shock and less brushing at spring opening.
Flush Brass Anchors
Solid brass anchors thread down flush with the deck for swim season. No stubbed toes, no rust stains on concrete or pavers.
Complete Install Kit
Ships with brass anchors, stainless steel springs, the installation rod, and a storage bag, so nothing else is needed on install day.
Tamper-Proof Release
The cover cannot be unhooked without the installation rod, which keeps children from peeling back a corner while your back is turned.
Installation Notice
A safety cover only performs to ASTM F1346 when it is fully installed: every strap anchored into sound decking and tensioned per GLI's owner's instructions. Drill brass anchors only into concrete, stone, or pavers that can carry the load, and never leave the cover partially attached. A loose or half-strapped cover is not a safety barrier.

Frequently Asked Questions
What is the difference between Secur-A-Pool mesh and a solid GLI cover?
Secur-A-Pool is GLI's standard mesh cover: it gives 93% sun shade and lets rain and snowmelt drain straight through, so there is no cover pump and almost no winter maintenance. A solid cover such as HyPerLite blocks 100% of sunlight and keeps every drop of dirty water out of the pool, but the surface water has to leave through a drain panel or a cover pump. Pick mesh for convenience, solid for the cleanest possible spring water.
How do I pick the right size?
Order by your pool's water surface, not by the finished cover dimensions. This listing fits a 20' x 50' pool, and GLI sews the cover oversized so it overlaps the deck on all sides and anchors under tension. Measure at the waterline, match the listed size, and match the step or offset configuration in the title if your pool has one.
Can I install this myself?
Yes, if you are comfortable drilling your deck. You lay out the cover, drill the anchor holes, thread the stainless springs on the straps, and tension each strap with the included installation rod. Plan on a helper and an afternoon the first year. After the anchors are set, putting the cover on or taking it off takes only a few minutes each season.
Will water sit on top of the cover?
No. The mesh passes rain and melting snow through to the pool, so nothing ponds on the surface and no cover pump is needed. Fine silt and leaves stay on top, so blow or sweep the cover off before you pull it in spring.
What colors does Secur-A-Pool come in?
GLI offers Secur-A-Pool in Blue, Green, Gray, and Tan. Green is the standard stocking color, and the exact color of this cover is listed in the product title and the spec table above.
What does the warranty cover?
Secur-A-Pool carries a 15-year limited warranty with 3 years of full coverage against defects in material and workmanship. Keep your receipt and the owner's instructions, and follow the anchoring and tensioning steps: covers damaged by improper installation or by being left loose are not covered.

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.
