If you’ve spent any time fitting ventilation air valves, you’ll know the frustration. You cut your hole, go to fix the valve in place, and — without fail — the fixing holes in the spigot sit right on the crumbly edge of the ceiling. What should be a five-minute job turns into an on-site headache, leaving you improvising and hoping for the best.
Sound familiar? You’re not alone. It’s one of those installation annoyances that every HVAC engineer has dealt with for years. Until now.
Meet the Terlok Ring Leader®
The Ring Leader® is a simple, clever air valve fixing ring that solves this exact problem. Developed by Terlok and protected under Registered Design No. 6054133, it’s the kind of product that makes you wonder why nobody thought of it sooner.
Here’s how it works. Before you cut your ceiling hole, use the Ring Leader® as a template to mark the correct size opening — no guesswork, no measuring twice. Once your hole is cut, the Ring Leader® sits securely around it, giving you a solid fixing point for your air valve well away from the edge. The result is a secure, professional finish every time.
See It In Action
Sometimes the best way to understand a product is to see it being used. Watch the official Terlok Ring Leader® installation guide below — it really does speak for itself, particularly for solid ceiling installations:
