Universal Table Extension Kit – Under-Table Slide-Out Mechanism (210×320 mm)

The universal slide-out table extension mechanism is designed to make your folding table more functional and sturdy. It’s especially useful for drop-leaf tables (with a fold-out section) commonly found on yachts, RVs, and campers, where space is limited and the table needs to stow compactly.

How it Works:

• Under-Table Installation: The main sliding component of the kit is a flat stainless steel plate (approx. 210×320 mm) that mounts on the underside of the table – either under the folding leaf or under the main top, depending on your table’s design. When the table is folded down, the entire mechanism is hidden and invisible.
• Pull-Out Support: When you open up your table, you simply pull the rail mechanism outwards. It slides forward thanks to built-in tracks and bushings, and forms a support bar under the flipped-up section of your tabletop. In effect, it acts like an extra leg, but horizontal and out of sight.

Construction and Materials:

• Stainless Steel: The primary plate and sliding rails are made of high-quality stainless steel. This ensures the mechanism won’t rust or weaken even in damp, salty environments typical on boats. Additionally, the steel construction gives it a high load capacity – the extended leaf can bear weight (dishes, laptops, equipment) without sagging.
• POM Bushings: Between moving parts are polyacetal (POM) plastic bushings, which provide smooth and quiet sliding action. This material is self-lubricating and wear-resistant, meaning the mechanism won’t stick or develop play over time. The slide remains tight and wobble-free – your table will feel like one solid surface, without the extension flapping or bouncing.
• Dimensions: Its compact design (around 9 cm high, 7 cm wide, and 34 cm long overall) allows installation even in tight cavities beneath the table. The mounting holes are in a universal pattern, so it can adapt to various screw spacing depending on your tabletop’s thickness and material.

Installation:

• The kit comes ready to install – you’ll need to position it under the table such that the sliding part can extend in the correct direction (where the table’s fold-out leaf lies). Typically, this means mounting it under the main top, near the hinge of the drop-leaf, or under the drop-leaf itself, with a small handle or lip accessible to pull it out.
• It fastens with screws (not included, as the type depends on your tabletop material). It is recommended to use stainless steel screws for longevity. Once installed, the mechanism is invisible from above; from underneath or the side you might see a small grab handle or just the edge of the rail which you pull on to slide it out.

Usage:

• On Boats/Yachts: Salon tables often have a folding section to increase surface area during meals. With this mechanism, when you fold the table out, you have a reliable brace without having to deploy an additional leg that could obstruct legroom. This is particularly convenient in yacht saloons where space is tight – you get a large table only when needed, without the constant hindrance of extra supports.
• In RVs/Campers: The tight dining spaces in campers often require flip-up table extensions. The universal slide-out support holds the extended section firmly, so your family can use the full table area for dining or work without fear of it tipping. When the table is folded, the mechanism takes up no usable space and doesn’t spoil the look of your interior.
• Versatility: It’s suitable for any furniture with a fold-out surface – breakfast bar tops, drop-front desks, even home tables where you want extra support for a fold-out leaf. Its universal nature means it’s not just for marine use – you can use it at home if you have a table with a leaf that could benefit from better support.

Advantages:

• Provides stability and safety – your table’s extension won’t wobble or rely solely on hinges which might loosen. You can confidently place items, laptops, or dinnerware on the expanded section.
• Extends the life of your table – it eliminates stress on the hinges and tabletop edge, protecting them from bending or breaking under load.
• Inconspicuous and quiet – it won’t mar the interior aesthetics, nor will it rattle or squeak under way or during travel.

With this universal slide-out extension, you’re investing in a more convenient and reliable table. Install it once, and you’ll reap the benefits every time you open up your table for a family meal or friendly gathering on board or on the road.
