"We're not carpenters by any means, but my wife and I did this project entirely by ourselves. I'm 76 and she's 71 and it feels good to complete a project while adding value to our retirement home at the same time. I'm glad I found your product"

John Richard Campbell, FLA

"System is impressive - we were telling the folks at the Pro-desk at our Home Depot about them. I love them because I don't have to look at hideous lag bolts on the face of my deck. We made some decorative trim to cover the anchors so nothing it visible! We'll certainly be ordering more next year when the other deck is replaced."

Patty McSwain

"The Titan has it all. It's got the strength that is what you're looking for but the look is outstanding and combined with the other features I put on this railing system it was the right choice. And I'm happy about that."

Bob Evans, Rideau Lake

Use a 1.25" dia. hole saw (1-7/8" cut depth) to prepare post with a circular pilot cut to guide cutting edge of tube which is then driven into post as shown in installation video.


Base 5"x5"x5/8" (127mmx127mmx16mm)

Tube 1.25"x3.5" (32mmx89mm)

Base and tube size are optimally designed for nominal 4x4 (3.5"x3.5", 89mmx89mm) and true rough sawn 4x4 (100mmx100mm) post sizes.

Select a post without knots in lower 6" of post.

If used with dry wood (m.c. 12% or less) check cutting edge of tube is sharp as zinc can accumulate on edge. Use a circular metal file to reveal original factory edge to get good cutting action in drier wood.

Not intended for use with hardwoods or Doug Fir unless hardwood installation techniques are used as indicated in directions (download below). Hot dip galvanized and powder coated for superior performance.

Tested and approved according to IRC (AC273) and CBC building code procedures for use in residential guards for one and two family dwellings. Must use specified fastener package (3/8x5 and #14x3 screws). 6' max post spacing when used as guard rails.
