Festool Domino Sipo Outdoor Tenon Stock, 750 mm (29.5-in.)

Festool D 10x750/28 MAU DOMINO Sipo tenon stock is solid hardwood floating tenon stock for Festool DOMINO joinery systems. This is a DOMINO tenon stock designed for cutting custom loose tenons for mortise and tenon joinery, especially in outdoor applications. Model Number: 498691. If you use a DOMINO joiner and need strong, weather-resistant joints, this stock gives you the raw material to make tenons to the exact length your project calls for.

What sets this stock apart is the material. Festool makes it from solid Sipo, a rot-resistant mahogany species suited for exterior work where standard beech tenons are not the right fit. For outdoor furniture, entry gates, exterior trim, and similar projects, that matters. You are not just buying a wood strip cut to size. You are buying joinery stock chosen specifically for long-term durability in exposed conditions.

The 3/8" (10 mm) thickness pairs with larger DOMINO joinery setups, and the long 30" (750 mm) sections are meant to be cut to length based on your mortise depth and joint design. That gives you flexibility when you are building custom frames, rail-and-stile assemblies, or larger furniture parts. Instead of working around a preset tenon length, you can size each piece to the joint so the fit makes sense for the stock thickness and the load the joint will carry.

Festool also uses the familiar DOMINO profile that helps the tenon function as a true floating tenon. The flat, elongated shape resists rotation, which is exactly what you want during glue-up. On edge joints and face joints, keeping parts from shifting saves time and frustration. The embossed surface and glue pockets are there for a reason too: they help distribute adhesive and leave room for excess glue so the joint seats properly.

In practical use, Festool specifically notes that the tenon should be cut 1/16" to 1/8" (2 to 3 mm) shorter than the mortise depth to create a glue pocket. That small detail matters because it helps avoid hydraulic lock and gives glue somewhere to go when the joint comes together. It is the kind of thing that separates a clean assembly from a joint that fights you during clamping.

This tenon stock is suitable for the Festool DF 500 and DF 700 DOMINO joiners. That compatibility is important for shops that run more than one DOMINO machine or want one stock option that can serve different setups depending on cutter size and project scale. Because these are long sections rather than pre-cut loose tenons, they are especially useful for woodworkers and tradespeople who want more control over joinery length on custom work.

The pack includes 28 pieces, each measuring 10 mm x 30" x 15/16" (750 x 23.9 mm). Festool also lists the material as FSC-certified Sipo. For cabinetmakers, furniture builders, finish carpenters, and serious DIY woodworkers doing exterior or moisture-exposed work, this is a smart pickup. If your project lives indoors full time, standard indoor tenons may be enough. If the joint has to hold up outside, this is the better answer.

Festool D 10x750/28 MAU DOMINO Sipo tenon stock is the right call for outdoor DOMINO work

If you are building outside and still want clean, repeatable DOMINO joinery, this is the stock that makes sense.

• Who it's for: Woodworkers, carpenters, and furniture builders using Festool DF 500 or DF 700 joiners for exterior projects.
• Why it stands out: Solid Sipo gives you outdoor durability, and the long cut-to-length format gives you more flexibility than fixed-length tenons.
• Worth knowing: This is stock, not pre-cut tenons. That is a plus if you want control, but you do need to size each piece correctly for the mortise.

• What Festool machines is this tenon stock suitable for? Festool lists it as suitable for the DF 500 and DF 700 DOMINO joiners.
• Is this meant for outdoor use? Yes. Festool states that the solid Sipo stock is intended for outdoor applications and is naturally rot and insect resistant.
• Do you cut these to size yourself? Yes. Each piece is a 30" (750 mm) section made to be cut to length for the joint you are building.
• Why should the tenon be a little shorter than the mortise depth? Festool recommends cutting it 1/16" to 1/8" (2 to 3 mm) shorter to create a glue pocket.
