Model 2 Lines 5 LInes

Setting fence posts straight by eye across 80 linear feet of uneven ground is how you end up tearing out every third post once the string line goes up. I've done that rework, two hours of dig-and-reset on a six-panel cedar run because the reference I trusted drifted half an inch per bay over soft soil. The fix isn't a better eye; it's a fixed green cross beam that holds plumb and level simultaneously from the first post to the last.

That's what the PostAlign does. This laser leveler for fence posts projects a high-visibility green cross beam that self-levels within ±4° in 3–5 seconds, giving you a locked plumb line down the post face and a level reference across the run, both at once, without a helper. The rechargeable 18650 battery runs up to 12 hours, so a full day of setting posts on a property line doesn't require a mid-job charge hunt.

400% Brighter than red beam

What Makes PostAlign Different for Outdoor Post Work:

Green Beam in Direct Sun Green wavelength is 400% more visible than red in daylight, the plumb line stays readable on a sun-facing post face without shading the unit.

Cross Beam = Two Checks at Once Horizontal line confirms the post top height relative to adjacent posts; vertical line confirms plumb face, one shot, both axes verified before you pack the concrete.

12-Hour Rechargeable Battery The built-in 18650 lithium cell outlasts a full installation day, no AA swap mid-afternoon when you're 40 posts into a property line run.

Solo Operation by Design Set it on the ground or a stake at the start of the run; the self-leveling system locks and holds while you work the post, no one needed at the laser end.

The compact form factor matters here: this unit sits low to the ground on uneven terrain without a tripod. For longer runs where you want elevation, it threads directly onto any compatible stand from our levelling laser with tripod via the standard 5/8"-11 mount, no adapter block needed.

2-Line or 5-Line, Which PostAlign Is Right for Your Job?

Model	Lines	Best For	Self-Leveling	Battery
PostAlign 2	1 horizontal + 1 vertical	Straight fence runs, gate post pairs, single-wall alignment	±4° / 3–5 sec	18650 Li-ion / up to 12 hrs
PostAlign 5	2 horizontal + 3 vertical	Corner posts, multi-panel layouts, simultaneous height + plumb + perpendicular reference	±4° / 3–5 sec	18650 Li-ion / up to 12 hrs

For a straight single-run fence with no corners, the 2-line model covers everything you need. Choose the 5-line when the layout includes a corner, a gate opening that needs to be exactly square, or when you're setting posts for a pergola or structure where three reference planes matter at once.

Three Jobs Where PostAlign laser level Earns Its Place:

Property-line fence installation across uneven ground Soft soil and grade changes throw string lines off over long runs. A fixed green plumb line on each post face removes the guesswork, place, check, pack, move on.

Gate post pairs that need to be exactly plumb and at matched height A gate that doesn't swing true usually comes down to one post that's 3mm out of plumb, the cross beam catches that before the concrete sets.

Pergola or privacy screen post layout requiring square corners The 5-line model projects three vertical planes simultaneously, enough to confirm a 90° corner without measuring diagonals by tape between every pair.

If your fence layout has more than ten posts or a single corner, a green cross beam that self-levels in 3 seconds is faster than a string line and more forgiving than an eye check. PostAlign is the layout tool that stays put while you work the post.

FAQ - Laser level

What is a laser level and how does it work?

A laser level projects a beam of coherent light to establish a precise horizontal or vertical reference line across a surface. Self-leveling models use a magnetic pendulum dampened in fluid to find level automatically within ±4° of plumb a process that takes 3 to 5 seconds on most cross-line units.

If you place the tool on a surface inclined beyond that range, the beam flashes as an out-of-level warning rather than projecting a false line. This is a critical safety feature. Cross-line models cover interior rooms up to 65 feet without a detector. Rotary models spin the beam 360 degrees and reach 300+ feet outdoors with a compatible detector.

Is a green beam laser level worth the extra cost over a red beam?

For interior work in lit rooms, yes. Green beams emit at 505–525 nm a wavelength the human eye perceives as significantly brighter than the 630–680 nm red spectrum at identical power output. In a daylit room:
Green beam: stays readable at 50–65 feet without a detector
Red beam: fades to unreliable at 20–30 feet under the same conditions
The trade-off is battery life: green diodes draw more current and reduce runtime by 20–40% vs equivalent red models. For outdoor grading where you run a detector regardless, red beam's battery advantage matters more. For tile layout, cabinet runs, drop ceiling grids, and any daylit interior room, green beam justifies its cost at every price tier in the RayXact catalog.
