Built for the Measurements You Make Alone

Every part of the SpanLock is designed around one goal: measure once, cut once, no helper needed.

2.8 m Solo Standout

A 25 mm deeply curved steel blade reaches 9 ft 2 in unsupported, enough to clear a full 8-foot sheet without folding.

Zero-Creep Thumb Lock

The bright yellow cam lock clicks down under your thumb and held a 4 kg load with no measurable slip in our tests.

True-Zero End Hook

Double-riveted and precisely slotted, so inside and outside readings both match a machinist rule within 0.5 mm.

Drop-Resistant Case

The rounded matte-black ABS shell survived five 6-foot drops onto concrete with no cracks and no calibration change.

How the SpanLock Stays Straight and Accurate

A Blade Shaped to Resist Gravity

A Blade Shaped to Resist Gravity

The 25 mm high-carbon steel blade is cupped across its width, which stiffens it like a beam. That curve is what keeps it flat out to 2.8 m instead of twisting at 6 feet.

A Lock That Clamps, Not Rubs

A Lock That Clamps, Not Rubs

Press the yellow slide on top and a cam wedge pinches the blade against the case. It stays locked when bumped, dusted, or carried across the shop.

A Hook That Reads True Both Ways

A Hook That Reads True Both Ways

The silver hook slides by its own thickness on two steel rivets, so the zero point stays accurate whether you hook an edge or butt it against a wall.

Description

Designed for one-person layout.: Most tapes fold between 6 and 7 feet. The SpanLock's wide, cupped blade reaches 9 ft 2 in on its own, so you can measure plywood, drywall runs, and window openings without a helper.

Made to hold your number.: The yellow cam lock is easy to hit with gloves on and clamps the blade solid, so the measurement you took at the wall is the one you cut at the saw.

Easy on hands and eyes.: A rounded case that fits a medium hand, a wrist strap for ladder work, a matte blade that does not glare under LEDs, and a controlled return that will not snap at your fingers.

5–7 Day Shipping & 30-Day Returns

Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.

30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.

Care & Safety
  • Guide the blade back into the case with a finger instead of letting it free-retract. This protects the hook rivets and keeps your zero point accurate for years.
  • If the blade gets wet or dusty, wipe it with a dry cloth before retracting. A light wipe with a lightly oiled rag every few months keeps the coil smooth and rust-free.

Finally clears a full 8-foot sheet of plywood solo

Nothing makes me lose my mind faster than stretching a tape 7 feet to hook a stud by myself and watching it fold with two inches to go—five times in a row. Pulled the Cosari SpanLock out on my garage workbench and easily hit 9 feet of horizontal standout before it buckled. Having a full 10-meter (33ft) reach in a rounded shell that isn't any heavier than my old 25-footer saved me from pulling out the long reel tape on deck framing.

Dead-solid lock that doesn't creep on the walk to the miter saw

My old tape's slide lock creeps about a sixteenth of an inch while I walk from the baseboard to the miter saw. Cost me two pieces of oak trim before I figured out why my miters were short. That high-visibility yellow thumb lock on top of the SpanLock is so easy to hit with work gloves on, and when you push it down, the blade is clamped dead solid with zero slip.

No glare under my LED shop lights

The glare on glossy blades under overhead LED shop lights makes it impossible to read marks without tilting the tape back and forth. The matte yellow blade with bold black numbering on this Cosari is night-and-day easier for my 52-year-old eyes to read in a dim basement than shiny silver or glossy blades.

Survived a 6-foot ladder drop onto concrete

Dropped it off a 6-foot A-frame ladder onto the garage slab on day two—didn't crack the matte black case and the silver hook stayed true. Big brand 25ft tapes have turned into 2-pound bricks wrapped in useless rubber armor that tear the pocket right off your work pants. This rounded shell actually fits a normal human hand.

Doesn't twist like a wet noodle when reaching overhead

What I want is simple: a compact case that fits my palm, a lock that clicks down and stays put, and a blade that doesn't twist like a wet noodle when I'm measuring ceiling joists solo. The deep curve across this 25mm blade keeps it rigid past 9 feet every single time.

Smooth retraction all the way to the hook

Cheap tapes always lose tension on the last 18 inches after a month—you end up stuffing the blade back into the slot with your fingers. On the flip side, when a cheap 10m tape snaps back unbraked and clips your knuckle, you remember it for a week. This one winds back crisp and controlled all the way home.

Thumb lock is super positive, wrist strap is handy on ladders

Really like the positive click on the yellow top slide lock. Even with sawdust all over my hands, it grabs the blade tight. The black wrist strap at the back actually came in handy while I was up on scaffolding hanging fascia boards.

Bold numbers you can read from standing height

When you're laying out bottom plates on a subfloor, you don't want to kneel down for every mark. The contrast on the yellow blade is sharp enough that I can read it standing straight up even in early morning garage light.

Replaced both my 25ft pocket tape and my 35ft brick

Having a full 10 meters (33 feet) in a shell this manageable means I stopped carrying two separate tapes in my tool bags. The silver end-hook grabs cleanly on both inside and outside edges without sliding off.

Bought a second one so mine stays in the shop

After using it for two weekends framing out our basement utility room, I bought a second one at 50% off for the house tool drawer so my wife stops borrowing my shop tape and leaving it upstairs. Solid tool.

Frequently Asked Questions

How long and how wide is the blade?

The blade is a full 10 meters (33 feet) long and 25 mm wide, with a deep curve across its width that gave us 2.8 m (9 ft 2 in) of unsupported standout in testing.

Why does the end-hook move slightly?

That is on purpose. The hook slides by exactly its own thickness, so it reads true whether you are hooking an edge for an outside measurement or pushing it against a wall for an inside one.

Will the yellow slide lock slip over time?

It uses a high-friction cam wedge rather than a plastic dimple. In our test it held a 4 kg load at 150 cm with zero measurable creep, even after we coated it in MDF dust.

Is the blade hard to read under LED shop lights?

No. The blade has a low-glare matte yellow finish with bold black metric and imperial graduations, which our testers read faster than glossy blades under overhead LEDs.

Is a 10 m tape too bulky for one hand?

It weighs 410 g, but the rounded case fits a medium hand well, gloved or bare. Most of our testers found it more comfortable to hold than the larger 25-foot contractor tapes.

What if the spring or lock fails?

You have a 30-day money-back guarantee if it does not meet your expectations, plus a 2-year replacement warranty covering the spring and lock.
