If you are looking to install a shade sail in your yard, there are many options available. You can choose from a triangle shape to a square shape. Regardless of the shape you choose, the shade must be tied to the post by ropes, and the knot needs to be fastened tightly, so the shade sail stays at the right tension. Many people want to know what type of knot they should use for a shade sail.
When installing a shade sail, there are different ways to tie the sail to the posts and house. Most people use pulleys and knots like figure eight, the grandma, and the simple slip knot. Some people don’t use knots to fasten their shade sail and use metal anchor points like eyebolts and chains.
When looking for the best possible technique to keep your shade sail secure and the tension as taut as it should be, you need to choose a fastening option that works for you. There are many types of knots you can use to fasten a shade sail, so after doing a lot of research, we wanted to share the type of knots you should use for a shade sail.
What Type Of Knot Can I Use For Shade Sail?
While you are installing your shade sail, there are various knots you can use to tie the shade sail off. Each shade sail has holes called eyelids. You should have four of these holes when using square or rectangle shade sails and three if you use a triangle shade sail.
In each shade sail kit, you should have metal fasteners that you attach to the ropes and then attach to the sail and the posts or pipes. Depending you’re your preference, you can choose between several different types of knots to fasten your shade sail to the posts or anchor points. Here are some of the most common knots that you can use:
The Figure Eight
The figure-eight knot for fastening a shade sail is typically used when you have a pulley tie-off cleat attached to the three or four posts to which you will fasten the shade sail. This type of knot is also called a cleat hitch. Here is how you tie the figure eight or cleat hitch:
The first step is to loop the rope over both cleat points. Then hold the loose point of the rope in one hand, and with the other hand, you loop the rope over the top point, then cross it to the opposite side and loop it over the bottom point in a figure-eight pattern.
Repeat the figure eight loops twice. Then can then secure the knot with a locking half hitch. You loop the bottom of the rope over the top point of the cleat. This knot is also used to tie off a boat and keep it from drifting away.
The Grandma Knot
The grandma knot is simple; you pull the rope through the eyelid and make a simple knot (that looks like a pretzel) that you then loop over the cleat. To ensure your shade sail is properly fastened, you should remember to make a double knot before securing the rope to the cleat.
The grandma knot is also called the simple overhead knot, and it is called the grandma knot as it is the easiest knot to make. The problem with this knot is that the knots sometimes become so tight that you might not be able to get it loose again.
The Slip Knot
A slip knot is one of the preferred knots to use when attaching your shade sail to the finishing points, as it allows you to make adjustments but still keep your shade sail taut and secure. Here is how to make a slip knot:
Measure the right distance of where the knot must be attached to the finishing point. Then make a loop in the rope. The end side of the rope needs to go two full rotations around the rope; then, the end rope goes through the rotations through the loop side on the top.
The loop side will now be able to adjust, and you can make it tighter on the anchor point by putting more weight on the rope. The rope will tighten around the anchor point.
Can I Fasten My Shade Sail Without Using Knots?
If you are not good at knots or you don’t want to use rope that can deteriorate with time, there is a way to attach your shade sail to its finishing points using other metal hardware. Here is what you will need:
- Three or four metal chains
- D-shackles (if needed)
- Three or four eyebolts
- Three or four turnbuckles
How many of each component you use will depend on whether your sail has three or four anchor points.
You attach the anchor points (where your shade will be fastened). Some might be attached to the sides of your home, some might be on posts, or all might be on posts. You can also use eyebolts for this step. If some points need to be attached to your home, you need to measure the correct distance and height and install a strong metal hook where the chain can be attached.
You need to attach the chains to the finishing points using the s-shackles that you loop through the eyebolts or hook the chain on the metal hooks.
You now have to attach the turnbuckles to the eyelids of the shade sail. Then attach each turnbuckle to the chains. Don’t worry if the shade sail is not taut; you can adjust the turnbuckle to the desired tension when you are done securing the shade sail.
Now that you have put all three or four points up, you can go around and tighten the turnbuckles to get the desired tension. If that still doesn’t work, you can unhook the turnbuckle and move it higher on the chain.
Each situation and shade sail is different, so it might be best to get the help of an experienced DIYer if you are new to DIY projects. The knots are easy to make, and you can always adjust them as time goes on to keep the tension on the shade sail.

If you don’t want to use ropes but prefer chains, you can use chains, D-shackles, eyebolts, s-hooks, and turnbuckles to attach your shade sail to its finishing points. No matter what fastening method you use, you must ensure your shade sail stays taut, or a strong storm/wind might damage the shade sail. we have information for shade in windy areas here.
