The Festool 496803 Thin / Extended Triangular Delta Sanding Pad is a flat sanding pad accessory for the Festool RO 90 DX sander. This is a sanding pad designed for detail sanding in narrow spaces. Model Number 496803 gives your RO 90 DX a long, slim delta profile that helps you work into shutters, louvers, slats, railings, and other tight areas where a larger pad shape leaves material untouched.

What makes this accessory useful is not just the shape, but what that shape lets you do on the job. When you are cleaning up edges, profile transitions, or narrow recesses, a standard round pad can be too wide to reach the work cleanly. This thin extended triangular pad narrows the contact area so you can sand closer to corners and into restricted spaces with better control.

Festool rates it for use with 93 mm sanding abrasives, which keeps it tied into an established abrasive format instead of forcing you into a special one-off setup. If you already run the RO 90 DX for surface prep and finish sanding, this pad gives you another way to adapt the same machine for more detailed work. That saves time compared to switching to a separate dedicated detail sander for every small section.

The design is aimed at practical access rather than bulk removal. For trim, shutters, rail details, and similar work, the longer delta shape helps you reach farther into confined spots while keeping the pad stable on the surface. That is especially useful when you need to feather edges or clean up inside tight geometry without over-sanding the surrounding area.

This accessory is made from plastic and weighs about 0.25 lb, so it adds very little extra weight to the tool. That matters on detailed sanding tasks, because a light accessory is easier to guide accurately over small surfaces and awkward angles. Festool also lists this as a plate with an interchangeable sanding pad, reinforcing that it is meant to be part of a flexible sanding setup rather than a fixed, single-purpose attachment.

For buyers, the fit is straightforward: if you own a Festool RO 90 DX and regularly deal with narrow sanding work, this is the pad that makes that tool more useful. It is a good match for woodworkers, finish carpenters, cabinet installers, painters doing prep work, and auto-detail or refinishing users who need access to tighter contours. If most of your sanding is broad, flat stock, you will not use this every day. But when the job gets tight, this is the accessory that keeps the RO 90 DX in the game.

Festool 496803 Thin / Extended Triangular Delta Sanding Pad is the right add-on when the RO 90 DX needs to get surgical

This is a smart accessory for RO 90 DX owners who run into shutters, rails, louvers, and other tight sanding spots on a regular basis.
