About This Product

This screwable deck post anchor is designed to securely support a deck, shed or porch. It represents an advantageous substitute since it allows installation without having to dig or pour concrete. Its adjustable head up to 3 in height makes it easier to level the floor during construction. Its steel structure and its helical disc ensure its stability and since it sinks more than 42 in. into the ground, under the frost zone, it resists ground movements (freezing, thawing). The anchor screw adapts to several types of terrain: it supports up to 5 000 lbs of load in sandy soil and 3 500 lbs in clay soil. For use with 4 in. x 4 in. square posts. Do not use for fences.Tip: You can use ½ in reinforcing rod to determine if there are rocks or roots in your soil and to act as a guide when installing the screw anchor.

Highlights

  • Support a load up to 5 000 lbs in sandy soil and up to 3 500 lbs in clay soil
  • For use with 4 in. x 4 in. square posts
  • To be buried more than 42 in de ground, below freezing depth
  • Adjustment range of approximately 3 in.
  • Can be extended with a 24 in. extension (product # 10571)
  • Baked powder coating finish provides excellent rust resistance

                Answer This Question

                Hello, You don't need tools or machinery to install our piles, simply using a 2x4 piece of lumber and turning around. However it is possible to use our 1" adapter and a power tools such as 1" impact wrench to install them. For more details please contact us : info@pylex.com. Best Regards.

                  Product itself is nice with the attached adjustable bracket. I tried to screw it into the ground as instructed. But if you have rocky fill or soil you will have to hand do your hole all but 6”. That’s as far as I could screw it in and compact the pylon down. I’m sure in soil types without 1” size rocks and larger, this would be able to screw down 50”. The product overall accomplished deck post anchors below frost grade, but I could have also poured concrete after my rocky holes were dug. I will give the benefit of the doubt with 4 stars but beware of rocky soil types.

                  I ordered 10 of these for a few small decks we had. This was the first time we used anything like this. They did work well. I don't know how big or tall a deck I would build off of the Pylex Piles, but they worked great for our 5'x10'x30" tall deck. We did have to buy a 1" impact driver to install them and make our own bit/socket. I also had to contact the company directly to obtain the testing specifications before our city would permit us to use them, but they did pass all the building codes in our area.

                  Hello, Helical Pile 1'' Installation Adapter (1-Socket) (10540) is also available online at Home Depot. The Pylex 50 installs very easily manually using a 2''x4'' board as lever. Thanks Pylex

                  Great idea, terrible construction / metal fabrication
                  I bought to anchor in a post in Upstate NY (where soil is about 18 inches of clay before a few feet of sandy loam). I followed all instructions, and probing the ground with rebar to over five feet to make sure no rocks were obstructing (they were not). Everything was working like a dream for the first two feet - but as I turned (using 2x4 per instructions) for the final foot, the entire shaft of the pile simply warped and broke into pieces - pictures attached. I can only assume that this was either a fabrication issue (as reading the reviews now others seem to have had similar failures), or the gauge of the design is too thin and simply gets stressed after driving down a few feet. I'm really upset not only because my project is now delayed, but I have no idea how I will be able to remove the existing broken pile out of the space I need (pipe wrench will be first attempt, but have to imagine its going to break more under that strain). Overall good idea, but I wish I bought a better brand.

                    Waste of time
                    waste of my time and money! I poured countless hours into installing these for my sauna, only to watch them fail miserably. After a measly 5 inches of embedment—without even encountering rock or any barrier—they collapsed, shattering any trust I had in this product. The welding is appallingly weak, no quality control. A jagged metal remnant is now lodged in the ground, forcing me to embark on a grueling excavation mission just to remove it and replace it with a new pile. Even if I manage to install the remaining piles to the required depth, how long will they endure under the load before they failed? waste of time and resources—avoid these at all costs!

                    Hello Sir,
                    In 28 years of sale we never heard such story where the welding broke at 5 inches in the ground, so I'm curious to see what happened in your situation, please send us a email or give us a call : 800-264-1881 or info@pylex.com. Thanks Pylex
                      Poor quality, not suited to most soils.
                      Breaks too easily with a 2x4x8, gets caught up on inch sized rocks. Do not recommend, broken 6 saddles welds driving in 3 piles in non-rocky soil hammering when stuck.

                        Do not use in clay soil
                        We bought them to anchor our pergola in Ontario. We only managed to put one fully in the ground. We put two other ones and they stopped going down after 3’. No matter what we tried they wouldn’t bulge. We then tried to “unscrew” them from the ground and it didn’t work. We ended up having to dig them out. The thread actually collapsed on itself so they are unusable. We now have to find another solution as the soil is loose where the posts were supposed to be. I would not recommend on clay soil at all.

                        We are curious to know how the tfread collapsed as per installation instruction you are supposed to remove the set screw, unscrew the big nut and then the head will insert into piles like a male-female connection.

                          Recommend to anyone
                          Very simple to install being one person. The soil in the backyard is mainly clay but it was still easy to hand turn with a 2x4. I’d recommend these to anyone and professionals as well. The time saving and cost saving is pretty huge vs machine drilled and concrete/tube pour.

                            This Metal Post was good to hold Up my clothesline, stronger. I put it in Concrete because of a vandal broke the same 4 x 4. I sold it flat and put it on a metal spike that goes in the ground And also in Concrete. I dug deep enough to keep it strong

                            Good value, but a delicate product
                            Needs to be made of heavier gauge material. References are made to using a "3/4" impact socket connected to a 1" impact driver to drive the ground screw, but the inside dimension of the cap is such that the 3/4" impact socket fits quite loose. We had to incorporate metal shims to keep it from rounding out the inside of the ground screw once it started hitting harder soil. Beam receiver metal is too thin gauge and welds broke upon compacting with a sledge hammer although we used a 4x4 block.

                            We do not recommend to install them from the inside but using a adapter that will cover the piles from the outside. The piles isn't meant to be installed using a 3/4" impact wrench. Please send us a email and we will let you know the recommended installation method using a impact wrench : info@pylex.com.
