I need one 90-Degree corner post and two mid posts. I see that the 90-Degree corner post comes with 4-1/2 in. x 4-1/2 in. but there is no 4-1/2 in. x 4-1/2 in. mid post. Can the 4 in. x 4-3/4 in. mid post or 4 in. x 5-1/2 fit with the 4-1/2 in. x 4-1/2 in. corner post?
Asked by: noname
Hi there, and thanks for your question. All of the post bases within the Peak Aluminum Railing system have a 4" x 4" post base. The additional size comes from the total foot print of the post. The brackets that are welded to the tops of the posts protrude out past the edge of the base, but the bases are all the same at 4" x4". We hope this is helpful. Please feel free to contact us at 877-883-7325 (toll free) should you have any other questions, or need any additional clarification. Thank you.

4-1/2 in. x 4-1/2 in. x 42 in. White Aluminum 90-Degree Corner Post is rated 4.0 out of 5 by 4.

Put it into concrete with lag's and had to cut to fit on small side porch. 5 posts, 3 railing runs and stair rail took around 8 hours (stair railing took the most time and see stair rail review for why it took so long). It looks really good and is solid. My only tip that the instructions don't mention well, and the videos don't show, is the base rail comes with a plastic strip that locks the balusters in place . Be careful when you cut the railing that the drain holes still line up. If you have to make more than a couple cuts, I would recommend using a miter saw with metal blade for aluminum. A hacksaw will work, but it is good thick aluminum so it will take some work.

Rated 5 out of 5 by from Best customer service ever Just finished 12x16 deck, happy I found Peak Railing on Home Depot .com. Good price, easy to install, looks like a professional install. Best of all, one of the post I received was damaged due to poor packing. I went on Peaks web page, filled out contact form. They called me next day and sent out replacement overnight express. Peak called back again to make sure I received the new post and if it was in good condition. In this day and age you just don't find that good customer service. A big thanks to the folks at Peak, great product, best customer service ever! I'm happy, happy, happy.

Rated 4 out of 5 by from Good Choice As a contractor this product was easy to install, sturdy and nicely detailed. It is a good alternative to having a fabricator custom build the railing. A decent low budget solution. A bit more labor than pre-built panels but easy enough. One caution - don't lose any screws it doesn't come with any extras. Best to have it delivered to store to pick up at your convenience. Had to block out a two hour window and they showed up with a 40' semi for a 90 lb. package. The driver was very courteous, professional and made it within the two hour window.
