Spectra Precision 105516 Vertical Adapter for HL700, HL750, HL750U HL760 Receiver for Vertical Applications

The Spectra Precision 105516 Vertical Adapter is a precision-engineered mounting accessory that enables contractors and surveyors to instantly convert their HL-series laser receivers from horizontal rod-mounted use to vertical-plane laser applications — no re-calibration, no extra hardware, and no wasted time on the job site. Designed for professionals who demand flexibility from their equipment, the 105516 is a smart addition to any laser leveling kit.

Product Overview

Whether you're plumbing walls, aligning columns, setting grade on vertical structures, or transferring reference points from floor to ceiling, the 105516 vertical adapter eliminates the need to carry separate receivers for each application. Simply attach the adapter to your HL700, HL750, HL750U, or HL760 receiver and reorient your detection axis without breaking down your setup. The adapter accepts both standard tripod thread sizes, making it universally compatible with the mounting hardware already on your truck.

Frequently Asked Questions

Which receivers is the Spectra Precision 105516 compatible with?

The 105516 vertical adapter is designed for use with the Spectra Precision HL700, HL750, HL750U, and HL760 laser receivers. It is not confirmed compatible with receivers outside this series — consult Express Tools if you need to verify compatibility with another model.

Do I need any tools to attach the 105516 vertical adapter?

No. The 105516 features a tool-free mounting design that allows you to attach or remove the adapter quickly without any wrenches or hardware. This is especially useful when switching between horizontal and vertical tasks throughout the work day.

What thread sizes does the 105516 support?

The adapter includes integrated 5/8-11 and 1/4-20 threaded mounts, covering the two most common thread standards used on surveying tripods and grade rods on North American job sites.

Will using the vertical adapter affect my receiver's calibration?

No. The 105516 is a passive mechanical adapter — it physically reorients the receiver without interfering with its internal electronics or calibration settings. Your receiver will perform exactly as it was calibrated once the adapter is attached.
