The standard, or spirit, level has been around since approximately 1640, when it was invented by French scientist Melchisedech Thevenot. The design was modernized in the 1920s, and since then not much has changed to the basic principal.
Still, today’s crop of level tools shows that progress marches on. In a market that offers everything from bubbles to lasers to digital readouts, consumers are reading more and demanding more from their tools.
To meet the increasing demand of consumers—and sometimes create it—manufacturers are beginning to offer products that are stronger, more durable, more accurate and offer a variety of proprietary innovations.
According to the Home Improvement Research Institute (HIRI), 3.8 percent of homeowners reported buying levels in 2005, just ahead of hammers at 3.3 percent and behind toolboxes at 4.0 percent. HIRI also reported that sales of spirit (or bubble) levels increased from 43 percent to 53 percent of levels purchased between 2003 and 2005, while laser levels dropped from 48 percent to 38 percent during the same time period.
Stanley’s response to level demand is its latest FatMax line of levels. For the New Britain, Conn., tool maker, the decision to stay with the spirit level was simple.
“We’ve done a lot of research with a lot of pros—they always go back to the standard level,” said Ryan Blair, Stanley’s global product line manager for layout tools.
Blair said that people expect more from manufacturers today. “The consumer’s getting a little more savvy, they want more quality for the price. They don’t want a disposable tool—they want something they can hang on to, something they can trust,” he said.
The latest addition to Stanley’s FatMax line features all the key elements of the new level equation. “We beefed up the product,” said Blair. “We made it thicker and taller.”
Part of the strength equation for Stanley was to build up the product’s endcaps, making them stronger and able to absorb greater impact.
Add that stronger construction to the FatMax’s accented dual side vials and center MaxEdge vial, a bridged center vial to allow for a continuous marking edge, and the readability of the level increases. The FatMax level is accurate within .0005 inches.
The folks at Stanley had a few other additions to the level. After talking to professionals and conducting numerous bench tests, there was one theme the company kept hearing over and over again. “People wanted a real nice big hand grip,” said Blair. Stanley added two. They also added a magnetic version to the level, building real earth magnets into it.
For leading level company Kapro, one of the latest innovations involves durability. The company introduced the Zeus 990, which is described by the Lake Mills, Wis.-based company as “the toughest level in the world.”
“It’s three to six times stronger than the average level currently on the market,” said Tom Kaczor, national sales manager for Kapro Tools.
According to Kaczor, the Zeus can withstand an inordinate amount of damage—the kind that comes from getting thrown around a job site—while still staying true to its factory calibration.
“On the spirit levels, they are demanding higher and higher accuracy on the vials,” said Kaczor, who pointed out that their vials also meet the .0005 mm/meter accuracy rating, which Kaczor equated to half the thickness of a dime per 6 feet.
In the readability category, Kapro has added multiple features to its latest creation to make reading a level line easier than ever before. It started with the plumb site dual view vials, which all ows the user to easily gain a vertical level view while looking straight on at the level, which Kapro says increases accurate reading and eliminates neck and eye strain. The company moved on to a magnified center vial and finished it
