I post a little review on these. I was quite skeptical but gave these a go for one job about a month ago. 4 5'x16' banners and 1 10'x16' banner. All were mounted to a building, 2 on a brick wall the rest on stucco. This dealership had in the past always had us make them banners for these spots which they always installed themselves and there were literally hundreds of ragged out holes everywhere. My installer complained a little at first but moved forward installing with these and came up to me later saying he was super impressed. I have to admit, for flat mounted banners these give them a truly professional appearance and they stay incredibly smooth and flat with almost zero ripples.
Installing the ones on the brick wall was the slowest since we had to drill many dozens of holes into brick with a hammer drill. On the stucco, that was backed by 3/4" plywood internally so those just zipped right in with deck screws. I also increased the spacing suggested by Lind (sorry Lind but I personally felt the suggested spacing was overkill for this application). They have been up for over a month now and still look as perfect as the day we put them up. Time will tell how they fare a year down the road. Seemed odd just punching the springs hooks right through the banner this way but they seem to be incredibly secure.
On the numbers of banners this was quite an upcharge to pass on to the customer as well but I also assured him that these would make a very big difference in the appearance of the banners as well as eliminating making more new holes everytime they change the banners out. Also made sure he understoood that while the install cost this first time was high (charged them about $1500 for the springs and install) that the install cost on swapping the banners later would actually be drastically reduced since the springs just stay in the wall.
I need to get some better photos but here are a couple for now.
The folks at Lind who I dealt with (John and Jillian) were both very helpful, corteous and easy to work with on purchasing our first real test of these. I can say without hesitation at this point if you have an opportunity to pitch these to a client, give them a try. My customer loves how the banners look now and while you can see the springs they actually look much more professional and secure than a bunch of random screws with big fender washers around the edges. I will be reccomending these to other clients on future projects. Oh and on the design..... this place has their own in house guy, not my design. lol
