## What is PullCalc?

Greenlee continues to drive efficiency with PullCalc, an app that helps electricians and contractors approximate the pull force needed to install an electrical cable inside of conduit.

Data is entered by "legs" and each leg is considered to be a straight run of conduit followed by a bend, except the last leg, which usually has no bend. The calculation for each leg requires the following information to be entered:
- Wire size
- Number of wires
- Conduit I.D.
- Duct Material
- Material of the Cable Insulation
- Coefficent of Friction*
- Length of Leg
- Bend angle
- Vertical Rise

*Due to unknown factors involved, it prohibits giving exact results, most notably the coefficient of friction. Lubrication, surface texture, and lay of the cable are never uniform along the length of a conduit run. Comparing the known forces of pulls against the estimated force should give you a guide as for a good coefficient of friction to use for similar future pulls, and a table with some suggested starting points for the coefficient of friction of well-lubricated cable is a drop down option in the app. If lubricant is not used, triple the values in the table.

## Key features

- Estimate pull force for cable installation
- Input data by conduit legs
- Supports various input parameters (wire size, conduit ID, bends)
- Includes coefficient of friction guidance
- Provides suggested friction coefficients for lubricated cable

### 4/5 — Please allow summary to be printed or emailed

*2015-05-23*

Great app for those who need to know approximate max pulling weight you will see at the puller end and to verify pulls to engineering. But the summary cannot be printed or emailed?

### 3/5 — Has Major Potential

*2015-03-05*

Great to see this app put out.  Would love to be able to select copper or aluminum and have more wire insulation types.  Also need to be able to put more than (4) for the quantities of conductors in the conduit.

### 5/5 — Good app

*2014-10-08*

Works well.

### 5/5 — Great Calculator!

*2014-08-18*

This is a great pulling calculator. Looking forward to future apps like this.

### 5/5 — Good app!

*2014-08-18*

A must download for users... Gives instant response, reduces manual error

### 5/5 — Finally!

*2014-08-18*

Easy to use, will help with all projects related to pulling wires.

## Frequently asked questions about PullCalc

### What is PullCalc used for?

PullCalc is designed to help electricians and contractors estimate the pull force needed when installing electrical cables inside conduit. It calculates this force based on various parameters of the conduit run.

### What information do I need to enter into PullCalc?

For each leg of the conduit, you need to enter wire size, number of wires, conduit I.D., duct material, cable insulation material, coefficient of friction, length of leg, bend angle, and vertical rise.

### Does PullCalc provide exact pull force results?

No, PullCalc provides an approximation. The app notes that exact results are prohibited due to unknown factors like lubrication and surface texture affecting the coefficient of friction.

### Does PullCalc offer guidance on the coefficient of friction?

Yes, PullCalc includes a dropdown option with suggested starting points for the coefficient of friction for well-lubricated cable. It also advises to triple these values if lubricant is not used.

### What devices is PullCalc available on?

PullCalc is available on iPhone and iPad devices. It is compatible with iOS devices.

### How often is PullCalc updated?

The latest version of PullCalc is 2.2, which was last updated on August 28, 2025. This indicates regular updates to the application.

### What is the user rating for PullCalc?

PullCalc has a rating of 4.0 stars based on 3 user ratings. This suggests generally positive user feedback.

### Is PullCalc suitable for all ages?

PullCalc has an age rating of 4+, making it suitable for a wide range of users, including younger individuals involved in educational contexts or assisting professionals.

minor bug fixes

### 1.2.3 — 2016-11-09

Greenlee continues to drive efficiency by expanding PullCalc app now to use it with the new Greenlee Smart Pull. Now monitor pulling force, speed and distance in real time by connecting with Greenlee smart pull. One can enter the maximum cable tension that should not be exceeded during the pull and the App when connected to Smart pull will provide an instant early warning alert that will allow contractor to take timely action, avoiding rework.

• Yellow flashing alert to end user when you are > 80% of Maximum cable tension • Red flashing alert when you are > 100% of Maximum cable tension • Email data directly from phone • Social media integration
