Description
GLI HyPerLite 18' x 36' Rectangle w/ Flush Side Step Solid Pool Safety Cover, Green
Total sunblock, 30% lighter carry.
The GLI HyPerLite 18' x 36' Rectangle w/ Flush Side Step solid pool safety cover, Green (SKU PST-201836RELHSF48HYPGRNK) shuts out 100% of sunlight with PVC-coated polyester fabric that runs about 30% lighter than a standard solid cover, so you get total algae blackout without wrestling a heavyweight tarp across the deck. Surface water leaves through the patented Kleen-Screen mesh drain panel, which filters dirt and leaves out of the runoff, and covers built without a drain panel pair with a cover pump instead. This one is closeout stock at a closeout price, so it ships while supplies last, complete with brass anchors, commercial grade springs, installation rod, and storage bag under GLI's 15-year limited warranty.
Total Blackout Over the Water
HyPerLite's PVC-coated polyester fabric blocks 100% of sunlight, so algae gets nothing to work with between closing and opening. No light means no spring bloom, which usually means less shock, less brushing, and a shorter startup than any mesh cover can give you. The solid deck also keeps dirt, pollen, and organic runoff from ever reaching the water, so what you uncover in April is close to what you covered in October.
Kleen-Screen Drains the Surface
A solid cover has to move rain and snowmelt somewhere. GLI's patented Kleen-Screen drain is a fine mesh panel built into the solid fabric that pulls standing water off the surface while straining out dirt, leaves, and grit so only clean water passes into the pool. Covers ordered without a drain panel use an automatic cover pump instead. Either way, water never sits and stretches the fabric through a freeze and thaw cycle.
Lighter Fabric, Commercial Grade Springs
At roughly 30% lighter than standard solid cover material, HyPerLite is the solid cover you can still handle with two people instead of four. GLI pairs it with improved puncture resistance for falling branches, deer hooves, and animal claws, plus Pull-Tite commercial grade springs that hold tension season after season. The system ships with the installation rod, anchor key, and a storage bag for the swim months.
Who It's For
Cleanest Spring Openings
Nothing gets to the water: no light, no leaf tea, no runoff. If you hate opening to green water, a solid cover is the strongest answer.
Families With Kids & Pets
Anchored and tensioned to spec, HyPerLite meets or exceeds ASTM F1346-91 for manual safety covers and holds an adult's weight.
Heavy Debris Yards
Improved puncture resistance stands up to falling branches and animal traffic where a lighter mesh cover would take damage.
Closeout Shoppers
These are current-season covers at closeout pricing in one-off sizes and step layouts. When the size is gone, it is gone.
Why PST Customers Pick This
100% Sunlight Blockage
The solid PVC-coated polyester deck stops every ray, which shuts down algae growth under the cover through the entire off-season.
Patented Kleen-Screen Drain
A fine mesh drain panel clears standing water off the cover while filtering out the dirt and leaves that would otherwise wash into the pool.
30% Lighter To Handle
HyPerLite fabric is about 30% lighter than standard solid cover material, so seasonal install and removal stays a two-person job.
Pull-Tite Commercial Springs
Commercial grade springs come standard, holding even tension across every strap instead of stretching out after a couple of winters.
Complete Cover System
Ships with brass deck anchors, springs, the installation rod, anchor key, and a storage bag, so nothing else is needed on install day.
Closeout Pricing
Limited closeout stock in specific sizes and step configurations. Once this size sells out it will not be restocked at this price.
Installation Notice
A safety cover meets ASTM F1346 only when every strap is anchored into sound decking and tensioned per GLI's owner's instructions. Solid covers also depend on the pool staying filled to the level in the manual, since the water supports the cover under snow load. Never leave the cover partially attached, and never drain the pool under an installed solid cover.

Frequently Asked Questions
Why is this cover a closeout?
These are one-off HyPerLite covers in specific sizes, colors, and step layouts that were built for the season and are being cleared at closeout pricing. They are new, first-quality covers with the full 15-year GLI warranty, not seconds or returns. Quantities are single units in most sizes, so once this listing sells out we cannot rebuild it at this price.
Does this cover have a Kleen-Screen drain panel or a cover pump?
Solid covers in this closeout run ship either with GLI's patented Kleen-Screen mesh drain panel sewn into the cover or paired with an automatic cover pump. Both solve the same problem, which is getting rain and snowmelt off the cover surface. Message the PST team with the model number listed above and we will confirm exactly which configuration this cover is before it ships.
How does a solid cover compare to mesh?
Solid HyPerLite blocks 100% of sunlight and keeps all dirt and runoff out of the pool, so spring water is as clean as it gets. Mesh such as GLI Secur-A-Pool blocks 93% and lets water pass straight through, which means less maintenance but dirtier water at opening. Choose solid if you want the best possible spring startup, mesh if you want the least winter attention.
How do I pick the right size?
Order by your pool's water surface, not the finished cover dimensions. This listing fits a 18' x 36' pool and is sewn oversized so it overlaps the deck and anchors under tension. Match the step or offset configuration in the title too, since closeout covers are built for one specific layout and cannot be modified.
Can I install this myself?
Yes, with a helper and an afternoon. You lay the cover out, drill the anchor holes in the deck, thread the springs on the straps, and tension each strap with the included installation rod. Once the anchors are set, seasonal on and off is a few minutes' work. If your deck is stamped or specialty concrete, a professional installer is the safer call.
What warranty comes with a closeout cover?
The same as a made-to-order HyPerLite: a 15-year limited warranty with 3 years of full coverage against defects in material and workmanship. Keep your receipt, follow the owner's instructions for anchoring, tensioning, and pool water level, and register the cover after purchase.

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.
