The new and enhanced lever handles from Carl F International install in just 7 seconds. The secret is an industry-changing invention called 'Fit in Seven Seconds' – an interconnection object attached to the inside of the lever handels. 'Fit in 7 Seconds' makes it possible to install any d line handle in one step, without the use of tools or screws.

"To Pihl – a major leading building contractor - the invention of 'Fit in Seven Seconds' will make a big difference.
I expect that during this project, constructing a bank domicile, we will be able to let one man mount the 500 handles within the last couple of days before handing over the building. I believe this system will save us approximately 120 man-hours.
Furthermore it is extremely easy to mount, you don´t need any tools, and the mouting doesn´t entail any need of cleaning afterwards as the old fashioned way of fitting door handles did.

An easier mounting minimizes our risk
Saving time and money is extremely important to the construction industry these days, and saving workmen hours is critical to the profitability of any building project. 'Fit in Seven Seconds' could save all our big clients a lot of money – money that can be spent on other upgrades or taken directly to the bottom line."
