          It would not. It has 3 matching holes to line up with the holes on the mailbox, then you would need to screw them in. I believe the Gibraltar mailbox requires a peel and stick type method. You may want to look it up if you have not already.... Good luck.

                  I’m not familiar with the Rubber Maid mailbox, however this Flag will fit any mailbox that has a side wall thickness of approximately 1/16 of an inch or less. Hope this has been helpful.

                      Not sure. The flag might be about 8" long and is engineered to be installed on the right side of the box, whatever you're using. I used it on the right side of a large plastic bin for my FedEx/UPS deliveries. I do not see any reason it would not work for your smaller box. You may have to go out and get a machine screw, washer and nut to properly secure it to the side of your box (which I just happened to already have, so it wasn't a big deal).

                          Will this flag fit any Gibraltar mailbox? The Gibraltar mailbox I have (plastic) is no longer carried at Home Depot. The flag was metal with a plastic bracket. The bracket has broken.

                            I can't say for sure. I'm in a gated community where all mailboxes are the same (white plastic). Can't tell if they are Gibraltar brand, but this replacement flag worked great...attached with pin & clip included. Very pleased with it!

                                I am not sure. When I bought my flag they said it would fit the Rubbermaid boxes from the 80's. I couldn't fit the lock part at the bottom of the flag because the box is different. So I just improvised. It is not the prettiest but it works.

                                  This Flag kit will fit any mailbox that has a 1/2 inch diameter hole in the side. On any application the Red Flag has loose clearances and may not stay up when raised. I “tweaked” mine by adding rubber washers to create some tightness so the flag will stay up but is easily lowered when desired.

                                    It does not fit plastic mailbox #GMB515B01. We tried several replacement flags but none worked......not even the one recommended by Gibraltar! We ended up buying a new mailbox.

                                      I couldn't make it fit. Disappointing and unexpected, as I had bought the mailbox (some years ago) from Home Depot. Their replacement flag didn't fit their own mailbox!

                                      My mailbox had been in use for 39 years and it was time to upgrade. I was surprised to find the exact flag system at Home Depot. See before and after photos.
