Probably not, with those brackets the opener is actually holding the top panel shut, without a traditional opener the top panel will not shut because nothing is pushing on the top panel and those brackets aren't going to extent by themselves
Don't get me wrong. The use of Super Sneakys are a great idea to solve a low headroom problem However, it can cause another problem. That is, a small obstruction (child leg) under the door will maybe cause the opener to not reverse reliably. The top section panel (with the Super Sneakys installed) now has the "downward" back pressure very much reduced from the opener. The opener "pressure" or force is now mostly horizontal, folding the hinge up to close the top section. There is a area where the opener may not sense an obstruction correctly. Because the opener needs to sense the vertical back pressure from an obstruction the safety aspect is contravened. Beware Americans. Blessings from New Zealand
