Series 550 Rafter Support Kits
The Series 550 Rafter Support Kits are engineered to provide your GrowSpan Series 550 High Tunnel Greenhouse with dependable structural reinforcement, making them ideal for growers in areas with heavy snow loads, high winds, or extreme weather conditions. This essential greenhouse reinforcement kit helps ensure your structure stays strong and secure year-round, offering growers added protection and long-term peace of mind.
Each kit includes four inclined high tunnel rafter supports and a bottom truss chord, all designed to work together to significantly increase frame strength and overall stability. These components help reduce structural stress, minimize movement, and distribute snow and wind loads more evenly across the greenhouse. As a result, growers benefit from improved durability, enhanced safety, and extended lifespan of their greenhouse investment.
For optimal performance, one rafter support kit should be installed approximately every 13' along the structure. This recommended spacing provides consistent reinforcement and ensures your Series 550 High Tunnel can better withstand challenging weather environments.

Why Buy From Us
Here’s why hundreds of customers choose us — and why you might too.
I started Greenhouse Gurus after running into the same frustration so many people have when trying to buy a greenhouse. I’d call around looking for real answers, real guidance, or just someone who understood what I needed…
but very few picked up.
And the few times someone finally did, it felt like they couldn’t wait to get off the phone. What seemed to be a lack of interest — just another rushed conversation.
That’s when I realized something simple:
People deserve better. They deserve someone who actually cares about their project.
So I built the type of company I wish existed when I was shopping. Today, Greenhouse Gurus is run by a very small team — just a couple of us — working hands-on with every customer to make sure you get real help, not generic answers.
Here’s what you can expect from us:
• A real person who answers the phone and truly listens
• Someone who understands these greenhouses and helps you choose the right one
• Shipping included, so the price is always honest and clear
• We’ll try and beat any competitor’s price because your budget matters
• 30-Day Easy Returns — not happy with your product? We’ll take it back, no questions asked
• Support before, during, and after your purchase — from people who genuinely care
I built this business to be the place I wish existed when I was searching — a place where your greenhouse isn’t just another sale, it’s something we’re excited to help you build.
That’s the difference. That’s why we do this. And that’s what you can expect when you choose Greenhouse Gurus.
