rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location rolling offsets are used in the piping and sheet metal (duct work) trades, a rolling offset changes the elevation and locaton of the piping or duct usually by using two fittings to offset around obstacles. rolling offsets are used mostly when you are limited to the size of the fittings in order to change your elevation and location

### What is the formula for a rolling offset?

Offset=Square Root of Roll squared+ Rise squared
For Example:
To find the travel and run for a 45 degree rolling offset with a
roll of 11.5 inches and a rise of 15.5 inches:
Solution Steps:
Offset= Square Root of 11.5 inches squared +15.5 inches
squared
Offset= Square Root of 132.25 inches+240.25 inches
Offset= Square Root of 372.5 inches
Offset= 19.3 or 19 5/16 (closest 16th of an inch)

### How do you figure a 7 foot horizontal rolling offset?

A rolling offset is generally an offset requiring a change in 2
directions. Eg. A horizontal offset and a vertical change in
elevation. There is additional information required to answer the
question. What is the angle of the fittings being used for offset?
15 deg. 30. 45? What is the change in elevation?
If this is a flat (no change in elevation offset) using 45 deg.,
the offset dimension (7') is multiplied by 1.4142 which is the
secant and cosecant of 45 deg.
The result 7 ' x 1.4142 = 9'-10 13/16"
Again, this result is for a flat run of pipe. If we have a
rolling offset with a change in elevation of say 1'. We can use the
Pythagorean theorem (A2 +B2 = C2)
The result would be (1')2 + (9'-10 13/16")2 = 98.99812 sq.
ft.
The square root of 98.99812 is 9'-11 3/8"

### What is the formula for a rolling offset with 2 45's?

There are many types of rolling offsets. 2 common are rolling
offset using 45 degree fittings and a rolling offset using any
angle.
using 45's
Rise: elevation change
roll: run of the pipe moving to the left or right
Travel: the run of pipe to make the offset
Simple formula
Travel = SQRT((rise(squared) + Roll(squared) ) x 2)
rise = 10"
roll= 16"
Travel=?
travel= SQRT ( ((10 x 10) + (16 x 16)) x 2 )
travel= SQRT ( ((100) + (256)) x 2 )
travel= SQRT ( ( 356 ) x 2 )
travel= SQRT ( 712 )
Travel= 26.68333 or 26-11/16"

### What are the pros and cons of an offset handle on a walking cane?

there aren't many cons besides style. An offset handle is a
comfortable, easy to grasp style that will spread your weight
evenly over the shaft. It is a great option, although there are
many more that customers prefer because of the look. Many people
want to get away from the standard "hospital" look of an offset
handle.
If you like the offset for how easy it is to use, try a
derby-style handle or a fritz. They both have the straight handle,
and offer a lot of room for your fingers (another one of the pros
of an offset, it makes it great for people with arthritis)
