Trapezoid Desk Legs | Trapezium Set of 2

For wood, use plain wood screws directly into the wooden surface for the most simple and durable fitting method. A small 1-2mm pilot hole is suggested for hardwoods to ease the screw in and reduce the risk of cracking. In all of our table legs, we provide 4.5mm wood screws, suitable for most sized tables over 18mm thick. If you are building a large table, go as thick as a 5mm wood screw and maximise the length for your top to ensure the best engagement. Threaded inserts can be a good choice if your project requires assembly/disassembly of the legs many times or you are shipping off to a customer and want a more professional finish. We suggest using an M5 bolt / 5mm threaded insert to fit into our legs 6mm hole. This provides a little wiggle room for wood expansion and hole alignment. Box section leg placement is largely a matter of choice. If using with one of our desk tops, we recommend that you do not exceed an unsupported span of 1 metre. Consider one of our fixed desk frames if you need a longer span between legs. This will provide a cross beam to add the additional support required for your desk top.

These box section legs can hold up to 150kg for an optimally constructed desk or table top; structurally sound timber over 30mm thick with suitable fixings. Constructed from 75mm x 25mm furniture grade steel, TIG and MIG welded joints and an extra thick base plate. The legs are naturally extremely strong. The legs are individually fitted to the desk / table top with eight screws per leg. No direct bracing between the legs means heavier tables can be susceptible to lateral wobble. For projects over 150kg or those constructed of non-optimal materials, we can supply self-supporting table frames that do not rely on the top for structural support.

Desk / table height Industrial Box Section legs come in either 58cm or 78cm widths. As a rough guide the 58cm width legs can be used for desks / tables up to 120cm wide, and 78cm are suitable for tables from 100-150cm wide. That means in practice, most desks will be fine with the 58cm width legs. For tables that are between 100cm and 120cm wide you can choose the width of the frame based on whether you think having more or less of an overhang will look or fit better with the your space and the table's intended use.

Some Ikea, laminate or cheap veneer desk / table tops will not be made of solid wood, but instead have a chipboard, particleboard or sometimes even honeycomb or hollow structure inside. These materials will not be strong enough for you to screw into, and will likely degrade around the screw resulting in a wobble or potentially even dangerous table. Our premium Pinnacle desk tops are made from very solid MFC, so do suffer from this problem. You should check the product description to find out what these tabletops are made of, and if they are not solid wood or something strong like plywood then it might be best to choose one of our free standing table frames. As the table frames are freestanding themselves, you will not need to worry about getting a really strong attachment, and you may be able just to rest the top on the frame. Or if you want to secure the top to the frame, you can simply use glue or even some heavy-duty double-sided tape. If you would prefer to use some of our non-freestanding legs, then an excellent way to ensure you get a strong fixing would be to glue a piece of 24mm plywood, cut a bit smaller than your top surface, to the underside using a strong adhesive to then screw the legs into that.
