Perpendicular Sanding Guide (90-deg Edge Fence) for RIDGID 18V SubCompact Brushless Random Orbit Sander – Model R870651B

Perpendicular Sanding Guide (90° Edge Fence) for RIDGID 18V SubCompact Brushless Random Orbit Sander – Model R870651B

Stop free-handing “almost square” edges and pretending it’s fine. This Perpendicular Sanding Guide bolts onto your RIDGID 18V SubCompact Brushless Random Orbit Sander (Model # R870651B) and turns it into a reliable 90° edge-sanding machine—so your corners stay crisp, your faces stay flat, and your blood pressure stays reasonable.

Designed for clean, controlled edge sanding, this guide keeps your sander perpendicular to the work surface while you run along an edge—perfect for squaring up parts, refining joinery, cleaning up CNC edges, or breaking sharp corners without tipping and gouging your work.

What it does
* Maintains a true 90° sanding angle against your work surface
* Helps prevent rounded edges, uneven bevels, and rocking during sanding
* Adds stability and repeatability for cleaner results on edges and faces
* Ideal for cabinet parts, furniture components, small panels, trim, and shop jigs

Built for makers (and reality)
* 3D printed with durability in mind (shop-ready, not “toy printer” flimsy)
* Preassembled with hardware — no hunting for screws, no guessing
* Mounts directly to the sander body for a secure, repeatable setup
* Lightweight design keeps the tool maneuverable while adding the control you actually want

What you get:
* (1) Perpendicular Sanding Guide for RIDGID R870651B

Compatibility
*** Fits: RIDGID 18V SubCompact Brushless Random Orbit Sander – Model # R870651B
*** Not compatible with other models unless explicitly listed.

Notes (the honest stuff)
* This is a 3D printed accessory, so minor layer lines are normal and won’t affect function.
* Sander and sandpaper are not included (because of course they aren’t).
* Supplied hardware is captured within the bracket to prevent losing them during disas
* The bracket features a captured-hardware design that keeps the fasteners fully contained inside the body, making assembly quicker and preventing parts from getting lost in your shop abyss.

If you want edges that come out square without babysitting the tool, this guide is the cheat code. You’ll still have to sand… but at least you won’t have to sand twice.
