Lathem knows a thing or two about time clocks, especially the kind found in warehouses and factories across America. They've been in business over 100 years, and their model 2100HD keeps that tradition alive.

Lathem will even admit the these types of clocks will eventually be replaced, but for now there are still plenty of people around who still want to use them.

If your not familiar with their older mechanical time clocks, they worked well in harsh environments with their metal cases and metal typewheel stamps. The downsides included a loud "ka chunk" sound, constant time/date adjustments, and messy ribbon replacements.

This clock solves those issues.

You might find it interesting that people tend to purchase these clocks because they don't want something computerized. Not just because they're heavy duty. They just want something simple.

Well, the 2100HD is certainly simple. It is also easy to use, can be used by any number of employees, and works with any pay period.

Here's what comes in the package

  • (1) Lathem 2100HD time clock
  • (25) Lathem E8 time cards
  • (2) metal case keys
  • Users guide

Be aware the 2100HD does not calculate or total the hours on the time card. For that, you'll need to look at calculating time clocks instead.

The 2100HD is assembled in the United States using imported parts.

Who is it best for?

Employers with harsh environments. Warehouses, factories, machines shops, or anywhere as long as there's access to AC power, and the desire for simplicity.

How do employees clock in?

This part is still a little old school. Employees insert a special time card in the front slot, and align it with the center light until it turns green. The clock with automatically prints using a patented thermal printer.

How does it help prepare payroll?

Again, the 2100HD does not calculate hours. You'll have to add the hours manually. With just a few employees, that's okay. With a lot, it will take some time.
