Measure the available space
Measure the width and depth of the driveway where the shelter will be installed, allowing for the necessary clearances. This will help you determine whether a single-width or double-width shelter is best suited.

Measure the width of your vehicle
Measure the widest part of your vehicle, including side mirrors and any lateral accessories.

Measure the length of your vehicle
Measure from the front bumper to the rear bumper, including accessories such as a bike rack or hitch if applicable.

Measure the height of your vehicle
Measure from the ground to the highest point of the vehicle, taking into account antennas, roof bars, cargo boxes, racks, or any other installed accessories.

Allow for a safety margin
Leave about 60 cm (2 ft.) on each side of the vehicle to open the doors and move around easily. Also allow for extra clearance above the vehicle to prevent contact with the structure, especially if your vehicle has a high roof or added accessories.
All car shelters come with standard U-anchors, which are the basic anchors included with purchase.
However, these anchors are often insufficient to withstand the harsh weather conditions of Québec.
That’s why we recommend considering a few additional options to reinforce the stability of your shelter.
OPTION 1 – Permanent Anchors
These anchors are fixed directly into the ground and provide strong, durable stability.
Shelter Size | Permanent Anchors | Number of Sections (± 4–5 ft each) | Layout |
---|---|---|---|
8' | 4 | 2 sections | 2 anchors per side |
12' and 15' | 4 | 3 sections | 2 anchors per side |
16' | 4 | 4 sections | 2 anchors per side |
20' | 4 | 4 or 5 sections | 2 anchors per side |
24' and 25' | 6 | 5 or 6 sections | 2 anchors per side |
28' and 30' | 6 | 6 or 7 sections | 3 anchors per side |
32' and 35' | 6 | 7 or 8 sections | 3 anchors per side |
36' | 8 | 9 sections | 4 anchors per side |
40' | 8 | 8 or 10 sections | 4 anchors per side |
OPTION 2 – Temporary Anchors (Concrete Blocks)
You can purchase these at most hardware stores or local suppliers.
Trévi recommends using 6 blocks per section of 4 to 5 feet, which equals 3 blocks on each side.
Shelter Size | Concrete Blocks | Number of Sections (± 4–5 ft each) | Layout |
---|---|---|---|
8' | 12 | 2 sections | 3 blocks per side × 2 sections |
12' and 15' | 18 | 3 sections | 3 blocks per side × 3 sections |
16' | 24 | 4 sections | 3 blocks per side × 4 sections |
20' | 30 | 4 or 5 sections | 3 blocks per side × 5 sections |
24' and 25' | 36 | 5 or 6 sections | 3 blocks per side × 6 sections |
28' and 30' | 42 | 6 or 7 sections | 3 blocks per side × 7 sections |
32' and 35' | 48 | 7 or 8 sections | 3 blocks per side × 8 sections |
36' | 54 | 9 sections | 3 blocks per side × 9 sections |
40' | 60 | 8 or10 sections | 3 blocks per side × 10 sections |
OPTION 3 – Wind Straps
Easy installation
They are installed horizontally, about 3–4 feet from the ground, and are not dependent on the shelter’s height.
Simply attach two straps per shelter, one on each end.

ADVANTAGES
The Double Supra carport stands out for its curved roof, which acts as a natural windbreak. This shape allows for better air circulation around the structure, increasing its stability in exposed areas. A recommended choice for open areas or areas prone to strong gusts.
