Norm wants to caution anyone modifying their tunnel (or any structure) as this compromises the entire concept of the structure as well as voids the warranty and can start a whole host of other issues. Please call and speak directly with Norm, as well as read ALL the material on our website and installation manual before embarking on what can be economical and easy to use season extenders, or, very costly mistakes. Thank you for your interest
One of our most popular structures is the hanley tunnel because it is the cheapest way of covering an area for season extension.
As a way of addressing some of the challenges and limiting factors with the tunnels, we have come up with a modified hanley.
The two areas where it significantly improves on the regular tunnel are the side clearance and the peak for snow shedding. Instead of using 24’ of steel to make 17’ wide and 7’6” high, we are using 26’ of material to make 16’ wide and 9’ high. It still uses 28’ wide plastic with extra at the ends to make the same kind of “tails”.
Sliding the plastic up on the sides is still the way that the tunnel is ventilated and you will still have the same challenges as far as creating access.
The re-bar anchors, base plates, clasps and rope are the same on the modified hanley as they are for the regular tunnel. We supply 5’ more of extra plastic for the tails since the building is taller.
The peak on the end hoops are very hard on the plastic, so we have designed a more rounded hoop at each end. It is strongly recommended to have 3 guides ropes at each end to brace back to the anchoring posts of the plastic.
Any structure with ends is not considered a Hanley Tunnel. We are more than willing to discuss the differences and benefits/drawbacks between tunnels and cold frames should you wish to know more.
The main thing which is critical to understand before going with a modified hanley is the extra wind load which the structure will be subjected to. Going from 7’6” to 9’ high, results in a 40% increase in the wind load. This issue is what makes the correct tightness of the ropes an even more critical consideration.
It is also the reason why we strongly urge customers who
do not have any tunnel experience to start with a regular tunnel.
The first area to discuss regarding season extension are those structures that are simple enough to disassemble and relocate to another spot-primarily referring to Hanley Caterpillar Tunnels.
The real lure of these buildings is their low cost and simplicity to move. Generally the area is prepared in advance and then the tunnel is moved over the area when the planting is to be done.
Since the original design specified 6′ hoop spacing, the intent was always to remove the cover before risk of heavier snow fall. More often now, growers are going to 5′ spacing (and sometimes 4′) to allow the covers to remain on longer or even permanently.
By having a smaller hoop spacing, it allows the cover to stay on permanently, which allows for a much earlier start in the spring.
The key to the concept of the hanley working is in the rope.
- The back and forth pattern of the rope resembles the way a person would lace up a boot.
- Typically there is a spring loaded clip at the base where the rope passes through.
- Once the rope is fully installed, it is important to tighten it through three passes from end to end.
- If the rope is not tight enough, the wind will create wiggle and movement sideways.
- When the plastic is tight enough, it also allows the grower to slide the plastic up the hoop to allow ventilation.
Generally the plastic is about 25′ longer then the tunnel.
This allows the installer to bunch up (pig tail style) the extra poly at both ends between a pair of posts.
It is important to get the plastic as tight as possible lengthwise first.
There must also be a rope from the top of the last hoop to the tie off post.
There are a couple of challenges to consider with the hanley tunnels.
- One of these challenges is to create a proper entrance. Typically entrance is achieved by slightly lifting the plastic and ducking underneath.
- The other are of challenge is the low shoulder height of the structure. This restricts the use to a couple rows of taller items in the middle and a couple rows of shorter plants along the side. The width of the tunnel does lend itself to three regular size beds.
Once you have learned about the nuances of the hanley tunnels, and asked any questions that come up, you will be better prepared to have these efficient season extenders work for you and your application.
Feel free to look at our Hanley Application page for more information and photos, and give us a call with anything else you require.
We are pleased to have many happy customers these structures are working for, and look forward to you being next!

Norm shared some nostalgia after Coffee Time with Norm recently. Check out his story here:
As we recognize and celebrate Organic Week 2020, we want to share a popular article from our website. We thank the organic farmers that go the extra mile for land stewardship and are proud to partner with so many of them. We will be sharing and highlighting some key organic related articles all week. We hope you find them helpful!
There are many benefits to having a greenhouse structure for organic growing and housing. They are often used a season extender for protecting crops from the elements, blight, and fungus. Since Organic growers and farmers do not use pesticides, this type of protection is often required for some of the more sensitive crops.
The structures are easy to move to allow the expansion of the growing area.These structures can easily help to give you the opportunity to grow more crops in a limited area. What many of our customers also do, particularly with Hanley Caterpillar structures, is start growing the early crops under the protection of the structure, and as the crop is stable enough, they move the structure to be able to start the next planting.
Our structures are also used for organic livestock raising to ensure the animals have a healthy, safe and protected environment out of the elements. They are versatile structures, and only require the changing of clear to white plastic for the various uses. The environment allows the animals to have sunlight, but still get the shade they require.
The combination of the double layer of plastic, roll up sides, and inflator fan, on both the greenhouse and livestock shelters, helps to reduce condensation and keep the structure ventilated. We are excited to be working on a solar powered fan option for those off grid customers or if the structure is out in the field away from electricity as we know many of our organic growers and farmers are in these situations.
4/6/20 With the pandemic being such a rapidly evolving situation, Multi Shelter Solutions is being vigilant for new and changing requirements. Please stay tuned to our website and facebook pages for the most up to date information on restrictions and closures. Please read the following information carefully and fully. Thank you.

This page has a bit about Norm’s history and the experience and approach that we have to every project that comes to us from you! It includes our video series on Values as well as a link to the video of Norm’s Greenhouses 101 presentation. “We don’t sell you a greenhouse, we help you buy one!”
Don’t take our word for it, here’s what others are saying!
We have been so grateful for the encouraging words and testimonials that people have shared about their experiences with us, on all our social platforms, on the phone and in emails. We wanted to honour those and share them with you in one place. If you have any to add, feel free to reach out and we will share yours too!
We want to help you find your shelter solution…here’s why!
This page is an overview of why we do what we do and how. Similar to Why Choose Us? it goes into a bit more depth
We have a number of resources on our website to share all the ways and applications which Multi Shelter buildings can be used. Norm has been in the industry for over 45 years and often says there isn’t much he hasn’t seen, and loves the challenge of coming up with new solutions for creative applications.
We have done a flying building to help an apartment building construction, a building over a boat sailing on the St. Lawrence over winter, a round building for a creative workshop area…as well as all the standard uses we have!
Profiles & Space Requirements
This page discusses the various heights in from the side you can roughly expect from our buildings to help you plan. We don’t bend any steel before we get an order, so this can be slightly adjusted as well if your requirement doesn’t fall within the chart. Please contact Norm for these custom cases we can do, for no additional charge. It also discusses the shapes and pros and cons of each. Stay tuned to this page later this month for a video from Norm explaining this further
We would love to discuss your project with you and how a Multi Shelter can help fit what you need. Have a look around our site for information and pricing, as well as the descriptions of what Multi Shelters values and how we work with you on your project. We look forward to hearing from you!
