Product Information

Two other reasons rest on transportation and availability issues. Carrying and connecting two 8-foot lengths is easier than transporting a 16-foot length, especially if traversing woodland trails. The availability of long 4x4s at many small suppliers is often limited due to low demand, making splicing a necessity. Repair

Go ahead and place the extension into position. Before you will screw it in use a level to make sure the extension is as level as you can get it. This is a really important step as not making sure the extension is in place will cause problems for your fence later. 6. Screw The Extender Into PlaceJoining 4x4s together to extend their length can be as easy as a butt joint or as complex and elaborate as a keyed, double tenoned scarf joint. However, some cuts are better done where the timbers can be rolled easily and joints tested for alignment and fit. When working on posts under load or limited space, simpler connections are better. A slotted hole that is oval-shaped in the post and sleeve makes it easier for you to line up the holes on both sides and to get the bolt in place.

There are many reasons why you might want a removable fence post. Maybe you need to have a section of demountable fence. Maybe you need to use it as a bollard to keep unauthorized traffic out of an area. You might be wondering why this removable fence post design is only for areas that don’t get snow and ice. Similar butt joint reinforcement connections may be made using two to four biscuits inset into matching grooves cut into the ends of the 4x4s. Alternatively, cut a matching groove in the butt ends and glue in a wooden spline. Dowels, biscuits, and splines all reinforce the alignment and provide some lateral reinforcement. Our choice for the strongest and easiest way to join two 4×4 posts is a half-lap joint that is glued, plated, and bolted. Cutting a half lap into an existing fixed post is easier than all other cuts, except the butt joint. The two required cuts per post are simple and doable even with limited space.To connect the Simpson Strong-Tie (SST) or other pre-drilled plates to the 4x4s, align and level the posts with the plates and clamp everything tightly together. Some plates have a mid-line set of holes that can align with the joint and still have enough holes for screws. Off-set opposing plates by 1/2 the distance between rows of holes, that will make it easier to fasten them. Use appropriate fasteners like SST #9 x 2-1/2” structural-connector screws to attach the plates to the posts. A tapered scarf or scarph joint is a diagonal joint cut on a 1:8 to 1:12 slope and is as old as the half lap joint. It is commonly found in beams, skids or other horizontal members joined together with wooden pegs or bolts and plates. The scarf joint requires some modifications when used to extend a post. The simplest way to connect two 4x4s is with a butt joint. Trim the ends to be joined so they are square and smooth. Any angle, however small, can act as a shear line, and a smooth flat surface makes for a better connection.

If the original fence posts are painted then you will need to paint the extensions to match. You can do this before you attach them, but I think they are easier to paint after they are already attached. Make sure that you choose a day that is sunny and there is no rain in the upcoming forecast. A hollow 10” to 24” metal pipe, 1” to 1-1/2” in diameter, inserted into a hole drilled vertically into the center of the ends of the two 4×4 to be butt joined, provides additional lateral reinforcement. The pipe is secured into the vertical holes with construction adhesive. Two 1/2″ through bolts are inserted into the top and bottom post pieces in holes bored through the wood and pipe. Finding extenders for concrete posts may be a little tougher than other materials. Extenders for concrete posts will be made of metal, wood, or vinyl. They should look like these. They will be slotted on either side, so that fence panels will slide in and fit snugly. A glued, plated and bolted nibbed tapered scarf joint is stronger than a half lap but not as easy to cut in limited space. Although it too has two cuts per 4×4, accurate sawing is more difficult. The skill level and aesthetics of the finished joint influence the choice of connection. A poorly sawn joint won’t make for a strong connection. Conclusion When applied to posts that meet the requirements of BS8417:2012 - UC4 (Use Class 4). See guarantee for detailsLengths of 3/8” to 1-1/4” dowels can be used to add lateral strength to butt joints. Carefully measure to bore and align 1 to 4 holes in the ends of each 4×4 and drill the holes between 1” and 3” deep. Cut the dowels to lengths of 2” to 6”, sand the cuts, glue, and tap into place. After fitting the pieces together, just screw them into place. 5. Place The Extender On Top Of The Post
