To: BPB Mfg. Co.,
I recently promoted the use of your product [the Bazooka Bob] within our company due to the great results we were seeing when we went to verify the plumbness and square of some prefabricated modules.

(Excerpt From an Inter-Company Email)

I wanted to share with everyone a tool that has made a world of difference in our project. Here on the Ivanpah Solar Project, we are erecting 450' towers, and the last 110' are being built with five modules. Prior to using this tool, the ironworkers had plumb and square issues even when utilizing lasers, transits, survey support, etc. They started using a tool called the ‘Bazooka Plumb Bob.’ Since then, they have had negligible amounts of error. The end result is a plumb and square structure that prior to the Bazooka Plumb Bob, they couldn't accomplish with twice the effort using lasers, survey support, etc. I would HIGHLY recommend this tool to the ironworker crews.”

The Fastest Way to Plumb a Column

Buy Direct- USA, Canada & International


The BAZOOKA PLUMB BOB is a length-adjustable vertical level whose structure shields it from the effects of the elements. With parts machined to a tolerance of .0005", a working accuracy of .001" can be expected(LESS than a human hair). A powerful magnet, with 181lbs of pull force, attaches directly to the column or other work surface and holds the Bazooka Bob tight. A linear gauge at the base of the unit gives an instant readout for level. Simply lift & twist to release the Bazooka Bob easily & move to the next column.

The BAZOOKA BOB vs lasers:

The BAZOOKA BOB works directly on the work surface. 

What this means:

  • EFFICIENCY- Requires only 1 man to operate. No need for a man taking a standoff reading as with a laser. Save TIME & MONEY as the Bazooka Bob is over 2x faster than a laser & the extra man can be handling other duties.
  • ACCURACY-  to .001" & NEVER a standoff error as happens with a laser
  • SPEED- Over 2x faster than lasers. The BAZOOKA BOB gives an instant readout for level.
  • (Attachments available- Precast & Wall Hook & Form Hook)
  • More SPEED- using two BAZOOKA BOBS, both North/South & East/West readings can be taken at the same time by one man using the  pass through gauge on the rear of the Bazooka Bob. You'd need three men to do that with two lasers.

Customer Feedback

"Nothing else does what the Bazooka Bob does better. Not even close."


Our machined parts are milled to an accuracy of  .0005"

What this means to you is:

The Bazooka Bob is accurate to 1/1000”.
As good as even the most expensive lasers.
That's less than a human hair
Also, since the Bazooka Bob works directly on the work surface you will NEVER deal with a progressive error as happens with a laser.

How many times have we heard of people dropping their laser, only to discover later that it went out of calibration?

Most laser manufacturers advertise you can drop their laser from 2-3ft and still be good to go. REALLY? We had a Bazooka Bob drop 14 stories and still be on the job. REALLY!

No, we don't guarantee that kind of toughness, but the Bazooka Bob is built for the job. You don't need to pet it.

The Bazooka Bob is made of all metal construction. This makes for an instrument that will last & last....
We regularly get units in for inspection which are 30+ years old, still on the job and working great. 

With no electronic parts and well-thought out construction, the Bazooka Bob is built for the jobsite.

Your time is money. The speed and accuracy of the Bazooka Bob will save you both. We guarantee it.

The Bazooka Bob is designed to need little maintenance other than an occasional spritz with a lubricant. With minimal care, your Bazooka Bob will last as long as you. Maybe longer.
