SGST-W Single Gang Single Tone Piezo Siren, 105DB, 24VDC

If you’ve seen pictures of this item from other sites, it’s depicted as a clean unit front with no screw holes. The unit uses plastic covers for the screws which I confirmed before ordering. Unfortunately only 1 of the 4 caps on the 2 units I ordered actually fit. The other 3 would not seat properly and are prone to fall out. The distributor admitted this is a quality defect affecting all units they’ve seen so I could could get a refund but not a defect-free product. So unless you plan to leaves the screws uncovered you might want to skip this one.
