📐 1. How accurate is this stair tread jig for scribing?
Extremely accurate. The combination of rigid aluminum extrusions and the magnetic stop blocks ensures perfect parallel transfer of wall profiles. Users consistently achieve scribe lines within 1/32” — more than enough for professional finish carpentry. The adjustable damping locks your setting, so it doesn't shift while marking.
🪜 2. Can I use this tool for stairs with stringers that are not perfectly square?
Yes — that’s exactly what it’s designed for. Uneven walls and out‑of‑square stringers are common in older homes. The GOOBETTER gauge measures both the left and right side of each tread independently, and the spring‑loaded pins (via the extension system) conform to any irregular angle. You’ll get a perfect fit every time.
🧲 3. Are the magnetic stop blocks strong enough to stay attached to the jig?
Absolutely. The rare‑earth magnets are recessed into the blocks and provide a secure grip to both the jig body and any ferrous metal surface (like your table saw fence). When not in use, you can snap them onto the side of the tool — they won’t fall off during transport. No more digging for lost parts.
🏠 4. Can I use this for something other than stairs, like floating shelves or wainscoting?
Yes, many professionals use it as a general scribing and layout tool. Fit bookshelves against crooked walls, mark uneven cabinet toe kicks, or template countertops for tight corners. The expandable length (up to 60.5”) makes it perfect for large shelving units. It’s a true multi‑purpose carpentry jig.
✈️ 5. Is the aluminum body durable enough for daily job site use?
Yes — it’s made from 0.16” thick aircraft‑grade 6061 aluminum, which is lighter than steel but extremely rigid. The anodized coating resists scratches and corrosion. Contractors have reported using it for hundreds of staircases without any bending or loss of accuracy.
📦 6. Does the kit include everything I need out of the box?
Yes. The complete set includes: 3 extension bars (16”, 12”, 8”), 2 magnetic stop blocks, knobs and rubber washers (pre‑installed), and an Oxford cloth storage bag. No additional parts needed. Just unpack, assemble, and start scribing.
