Q. My worry is that these will rub through the canopy, how is this prevented?
A. The magnet and staff are clamped to the fabric with the plate below the fabric. Together they all move slightly with the wind but there is no friction because they do not move separately from each other. In eleven years there has never been a single complaint related to wear of the canopy fabric. At the end of the season you will see an impression in the fabric but no wear.
Q. Where can I buy replacement string?
A. The string is #18 Braided Nylon Masons Twine. It is available at most hardware stores and home improvement centers.
Q. When I install Seagull Stopper how do I reach the corners of my canopy that are not next to my dock?
A. You will need to use a ladder. An 8 ft. stepladder is usually sufficient. If you use a extension ladder be sure to wrap a towel around the rails where it will contact your canopy fabric so it does not cause damage.
Q. How long does it take to install Seagull Stopper?
A. It will probably take and hour the first time you install Seagull Stopper. Experienced installers take less than 1/2 hour. There are a few “tricks-of-the-trade that make installation faster. When you install the first staff assembly, attach the string and take the string along with the another staff assembly to the next corner. Repeat the process until all staffs and one level of the string are installed. Another pointer: when you wish to throw the spool of string from one side of the canopy to the other such as when you are creating the diagonal cross, free up just enough string from the spool to reach the other side then tie off the string on the spool so it does not unravel when you toss it across your canopy. A clove hitch knot on the spool works great. This is the same knot most boaters use to tie a boat to a dock post. If you are frustrated by the time it takes to install Seagull Stopper, remember you only install it once a year and you will not be washing your canopy throughout the summer.
