The two questions above need to be considered together because the answers relate to the amount of strength required for your application. There are several degrees of strength that can be achieved with the Banner Ups, and PowerTabs/ PowerTape system. We recommend that for indoor or light duty outdoor use you may use either Mini Banner Ups or Mini PowerTabs. In either case simply apply a mini tab directly to each corner of your banner and then use the tab’s center hole to fasten the rope. Similarly, for indoor or light duty outdoor you may use the Large Banner Ups or PowerTabs with the rope attached through the corner loop.
For the next degree of strength, use the large tabs with the rope through the center hole. This can be used for most outdoor situations with banners in the range of 8 foot length and under.
For the maximum strength, use both PowerTabs and PowerTape as described above. This is recommended for banners of lengths in excess of 8 feet or where maximum wind exposure is expected. Naturally no banner can be guaranteed to withstand all possible environmental conditions, but consider this strength data.
The strength of a rope when tied through the center hole of a mini tab or through the loop of a large tab will hold up to about 50 lbs of force. A rope tied through the center hole of a large Banner Ups or PowerTabs will hold up to about triple that force -150 lbs. With the addition of PowerTape that number goes to over 200 lbs of strength. That means when you use the PowerTabs/ PowerTape system on all four corners you can create super strong banners that can withstand up to 800 lbs of wind load!
