Simpson Strong Tie CPT66Z ZMAX Galvanised 6 x 6 Concealed Post Base

Love these. They are a good sturdy quality as is needed. Easy to fit and they keep the base of the post off the ground so less moisture can penetrate. Good bit of kit and worth the money.

Makes anchoring wooden pillars and posts far more simple and secure , setting out still has to be done properly . Also keeps the base out of puddles , fantastic product 👍

Look its a strong product, nothing wrong with quality. But a real pain to install I have a decent sized chop saw but it's not big enough to fit 6 inch post under making it really fiddly. I used circular saw and couldn't get deep enough to reach middle, so had to finish with hand saw and its not wide enough so real bit of messing to sort it. Just think about it before you commit to these.

Cutting the slot is best by handsaw in my opinion, nice a tight and neat

Done the job

Now these are fitted I'm very pleased with them however my suspicions about ease of fitting (or not) were confirmed!If you have a very large circular saw and a large pillar drill you'll be fine. Otherwise like me you'll have to use a circular saw, hand saw and chisel to make the cuts deep enough.Also the holes for the dowels need to be perfectly perpendicular to the post (assuming the post is plumb). No mean feet when drilling a 150mm hole! I had to make a jig, 11 out of 12 dowels went in with a lot of persuasion, had to leave one post with only 2 dowels.Having said all that they look very neat and they were the only ones I could find for 150mm posts. Also worth mentioning there is sway in the posts once fitted which is actually handy if you haven't managed to get your holes perfect to the mm and your base perfectly level!

As others have said, it is really hard work cutting the slot for the plate. And you certainly need to drill the holes for the dowels before you put the post in place, not just mark them. If you have the tools to insert this efficiently, it would be much more satisfying to cut a proper mortise and tenon joint. I wish I had. It would've been quicker, and looked much better.

Love the look of these! Not cheap, but same as elsewhere and quick delivery. Highly recommend.

Product ok but I have now recieved an invoice from Fedex for customs charges. There should be no customs charges within the EU. Not indicated in Product / Delivery information. DONOT USE!

I really like the appearance and structural integrity of these post bases. I used a total of (12) of these constructing porch posts on my new home several years ago. I used both the 8x8 version and the 6x6 version (but mostly the former). The hole pattern is the same for both.Cutting the 6-1/2 inch deep slots is the trickiest part, and I bit the bullet and used a large Makita 5402NA saw to cut them, using a specially made guide which I screwed to the bottom of the post. If I didn't have access to the big saw, I'd recommend using the largest saw you can get and build a guide to screw to the post bottom - then use a hand saw to extend the cut the full 6-1/2 inches.For drilling the holes, I used a fixture that I had built as a drill guide. I invested in this since I was using big, expensive 8x8 posts and I wanted accurate holes. It has three drill guides welded to a plate that match the hole pattern in the bracket. That worked perfectly. I just clamped it to the bottom of the post and drilled three holes. Pins lined up perfect each time. If you don't have a jig, just take your time drilling the holes straight following the manufacturer's instructions.

I used 4 of these post anchors to build a raw Cedar log arbor on a trex composite deck. I knew they would require a high level of carpentry skill to use, specifically on natural logs. The fabrication of all parts was very solid and the instructions were clear enough to use in an irregular way. Getting the three anchor rod holes properly aligned was the biggest challenge, and did require further adjustments of log height and wallowing out of 1 hole in each log. The rods and plate were incredibly strong, able to withstand excessive mallet pounding to align and sink rods. Once all rods were set through the timbers, the logs stood majestically in place.The clean look of the black cap below a standing timber creates an elegant shadow line and accent, plus I also know the log will not wick moisture or sway in high winds. This is a very nicely designed product.The one requirement not called out by the manufacturer (which I thought through before starting) is that this hardware needs longer than regular drill bits (7-12") to make good bolt and rod holes in the deck and lumber. Those long bits also came in handy for aligning the plate as a template for rod hole drilling, and for targeting the three rods through the lumber once set upright.This is a great product from a well established manufacturer. I highly recommend it to anyone building a structure atop an existing deck.

This is the neatest way to attach a post to a concrete surface. Having all of the engineering data for the building inspector helps too. A great product for a good price.
