What Size Do I Need?

You have decided you must have one of these fantastic hangers, but what size? Simply measure the post and match the hanger size that fits best. Because they are for square posts, you only need to measure one side.

Available sizes are ¾”, 1”, 1-1/4”, 1-3/8”, 1-1/2”, 3-1/2” and 4”.

Measure across one side of your post to select your size.

How to measurePro tips: The shim will allow for minor errors with the sizing. If the measurement is between two sizes, choose the larger of the two. If the next size up is more than 1/8” larger than your measurement, we may not have a good fit.

Tips & Considerations

By following these tips, you can ensure a secure and visually pleasing installation of your garden flag hook, enhancing both safety and overall enjoyment of your outdoor space.

Ensure that you select a hook that fits the dimensions of your square post accurately. Using the correct size hook ensures a secure and stable installation.

Allow sufficient space around the post for your hook to rotate into location. Approximately half of the post width clearance on all sides is a good guideline for maintaining an aesthetically pleasing and safe installation.

Periodically inspect to ensure the grip remains tight and secure.

The strength of the post is a crucial factor in determining the ultimate capacity of the hook. Consider the material and structural integrity of the post to ensure it can withstand the intended load.

Choose an appropriate location for mounting your garden flag hook. Avoid mounting at eye levels or areas people are likely to come into contact with the hook. Avoiding walkways prevents potential hazards. Be mindful of surroundings for both safety and visual appeal.

Consider the local weather conditions, especially strong winds, when installing your garden flag hook. Reinforce or remove the installation if necessary to withstand gusty weather and prevent damage to both the hook and the flag.

Unintended Use and Load Considerations:
Exercise caution to prevent unintended use of the garden flag hook and avoid hanging items that are excessively heavy or life-critical. Use the hook only for its designated purpose to maintain its structural integrity and prevent potential safety risks. Ensure that the load applied is within the recommended weight capacity, safeguarding both the hook and the surrounding environment.
