Net Cover Zig-Zag 15 and 40 mm — Route Around Light Arms and Mounts - Red Sea

The Red Sea Net Cover Zig-Zag kit lets your screen top step around a slim rim-mounted obstacle — typically an LED light arm, a feeder bracket or a cable — by offsetting the frame edge instead of cutting a hole in the mesh.

Official contents

Red Sea publishes the following parts list for R42085 — two sets, two clearances:

• ZigZag 15 left (F) — 1
• ZigZag 15 right (F) — 1
• ZigZag 40 left (F) — 1
• ZigZag 40 right (F) — 1

The 15 mm set handles narrow obstacles, the 40 mm set wider brackets. Both come in the same box and you use whichever suits your gear.

Our advice

Take your time. The Net Cover is a cut-it-yourself kit: go slowly. It goes together well, but it doesn't go together fast. And before you cut anything, watch the tutorial all the way through — everything is shown in it.

Measure the clearance you actually need before choosing between 15 and 40 mm. A light arm that swings needs more room than a fixed one.

Others in the same family

This kit fits the Red Sea Aquarium Net Cover. For bulky gear like a skimmer or overflow, you want the universal cut-out kit instead. Across a long span, extra hanging clips keep the frame from sagging.

Frequently asked questions

What's the difference between 15 mm and 40 mm?

It's the lateral clearance the piece creates to let equipment through. 15 mm suits narrow mounts, 40 mm thicker brackets. Both sets are in the box.

Zig-Zag or universal cut-out kit?

Zig-Zag for a slim obstacle the cover's edge can step around. Universal cut-out kit when you need to open a genuine rectangular pass-through for a skimmer or an overflow box.

Do I need one Zig-Zag per light arm?

Each detour uses one left-right set. So one box covers a single 15 mm obstacle and a single 40 mm one. For two obstacles of the same size you need two boxes — write to us with your setup if you're unsure.
