Merlin Dura-Mesh II 18' x 36' Rectangle w/ 1' Offset Step In-Ground Pool Safety Cover
Thicker mesh, stronger cover, cleaner spring.
The Merlin Dura-Mesh II Safety Cover for 18' x 36' Rectangle w/ 1' Offset Step pools (SKU PST-26MMGR, MPN 26MMGR) is a heat treated polypropylene mesh built 33% thicker and 68% stronger than standard mesh, backed by Merlin's 15-year warranty. The 6.4 oz per square yard weave delivers 95% shade and filters water down to 85 microns while rain and snowmelt drain straight through, so there is no cover pump and no standing water. Tensioned on Merlin's patented stainless steel springs and brass deck anchors, it meets or exceeds the ASTM F1346 safety cover standard.
Heat Treated Mesh
68% Stronger Than Standard Mesh
Dura-Mesh II is 33% thicker and 68% stronger than ordinary standard mesh, for better abrasion resistance, tear strength and burst strength. Merlin backs it for 15 years with the first 2 years full.
Drains Through
95% Shade, 85 Micron Filtration
The Dura-Mesh II weave blocks 95% of sunlight and filters water to 85 microns. Rain and melting snow drain straight through into the pool, which means no cover pump, no extension cord, and no pond on top of the cover for a child or pet to reach.
Patented Spring
Merlin's Patented Spring System
Every cover ships with Merlin's patented safety cover spring (US Patent 2021/0324931 A1), stainless steel buckles, protective spring covers and non-corrosive brass concrete deck anchors that retract flush when the cover is off. Straps are heavy duty and triple stitched into specially formulated polypropylene and nylon 2-ply webbing that crosses the pool in both directions. Stainless steel and wood deck anchors are available for decks that need them.
Who It's For
Homes With Kids & Pets
Anchored and tensioned, the cover is a taut physical barrier over the water, meeting or exceeding ASTM F1346, for the months the pool sits unattended.
In-Ground Winter Closings
The straightforward pick for a seasonal closing on any in-ground pool with a concrete deck to anchor into, from a 12 x 24 to a 30 x 60.
Second Homes and Rentals
There is no cover pump to power or babysit and no water bags to refill while the property sits empty, though Merlin calls for checking the pool water level monthly during snow season.
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. A water-bag winter tarp cannot do that.
33% Thicker Weave
Dura-Mesh II is 33% thicker and 68% stronger than standard mesh, with the industry's best mix of abrasion resistance, tear strength and burst strength.
No Cover Pump
Rain and snowmelt drain straight through the mesh into the pool, so there is never standing water to pump off the top.
Filters to 85 Microns
The tight weave screens debris at the surface, though Merlin notes some fine silt and dust can still reach the pool, so plan to vacuum at opening.
2-Ply Webbing
Heavy duty triple stitched straps run into polypropylene and nylon 2-ply webbing, with stainless steel buckles at every spring.
Complete Install Kit
Brass concrete anchors, stainless springs and spring covers, an allen wrench, installation rod, storage bag and instructions all ship in the box.
Anchor It Right
A safety cover only performs to ASTM F1346 when every anchor is set in sound concrete and every spring is tensioned to Merlin's instructions. Recheck tension after installation and periodically through the winter, keep the cover fully anchored whenever the pool is unattended, and do not allow anyone to walk on it.

Frequently Asked Questions
How is Dura-Mesh II different from ordinary standard mesh?
Dura-Mesh II is 33% thicker and 68% stronger than standard mesh at 6.4 oz per square yard, and it blocks 95% of sunlight while filtering to 85 microns. Merlin backs it with a 15-year limited warranty.
Should I get the Dura-Mesh II or the Solid XLS cover?
Mesh lets rain and snowmelt drain straight through with no pump, and it is lighter to handle twice a year. The Solid XLS is 11.5 oz vinyl coated polyester that blocks sunlight and keeps leaves and debris on top, but it moves water through a mesh drain panel or an automatic pump. Choose solid for heavy-debris yards and the cleanest opening, mesh for the lowest maintenance.
What size cover should I order?
Order by your pool's water dimensions. A 18' x 36' cover is built for a 18' x 36' 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 a safety cover myself?
Merlin strongly suggests that a qualified pool professional complete the initial installation, and improper installation can void the warranty. Installation means laying the cover out, drilling anchor sockets into the concrete deck with a hammer drill and masonry bit, setting the included brass anchors, then stretching each spring on with the included installation rod. Merlin also offers stainless steel and wood deck anchors at extra cost.
Do I need a cover pump?
No. Mesh drains rain and snowmelt straight through into the pool, so there is nothing standing on the surface to pump off. Leaves and debris stay on top where they dry out and blow or brush away.
Which colors does Dura-Mesh II come in?
Merlin makes Dura-Mesh II in blue, green, gray, tan and black. This listing is the color shown in the title, which is the color we stock for fast shipment.
What does the 15-year warranty cover?
Merlin backs Dura-Mesh II with a 15 year limited warranty, first 2 years full and the remainder prorated, against defects in materials and workmanship. Keep your proof of purchase and run any claim through PST Pool Supplies as your authorized dealer.
