CHIPTOOLZ Rafter Center-line Locator – Precision Centering for Rafters

Find the exact rafter center-line with confidence

The CHIPTOOLZ Rafter Center-line Locator is a practical companion for builders and DIY enthusiasts who want repeatable, on-point center marks before framing, cutting, or running lines. Its design focuses on clarity in challenging spaces, helping you locate the rafters’ true center-line even when access is limited by insulation or layered decking. The 3/4" radius indicator key guides your mark, so you can rely on a consistent reference point as you work through attic spaces or vaulted ceilings.

One of the standout capabilities is reach: the tool can reach rafters up to 3" away, which broadens practical use in tight or awkward layouts. It is compatible with plywood laid over skip sheathing and under insulation, making it a versatile option for both retrofits and new construction. The included alignment pin supports fast, repeatable setup, helping you align with confidence before committing to a layout line.

Key benefits

• Exact center-line identification on hidden rafters, every time.
• 3/4" radius indicator key keeps you anchored on the true center point.
• Effective reach to rafters as far as 3" away for versatile layouts.
• Works with plywood over skip sheathing and insulated vaulted ceilings, increasing flexibility on site.
• Includes an alignment pin for quick, repeatable setup.

Practical use cases

• Rafter centerline marking before rough-in framing, wiring runs, or panel installation.
• Attic and vaulted ceiling projects where insulation or decking adds complexity.
• Retrofits where traditional access to rafters is partially obstructed.
• Pre-layout checks to confirm alignment before cutting or nailing starts.

While results can vary with room layout and material conditions, the CHIPTOOLZ Rafter Center-line Locator is designed to offer practical, repeatable guidance that supports careful planning and accurate layout. Users may experience smoother workflows, especially in spaces with limited visibility or irregular rafter placement.
