Glossary of Common Commercial Roof Drain and Parts Terms

Posted by Hy-Tech Roof

 

When shopping for an industrial or commercial roof drain or replacement part, it is important to be clear with a manufacturer or distributor what you need. Otherwise, you may inadvertently end up with the wrong drain or part or the wrong size, leading to more time that your roof lacks the proper drainage solution.

To help, we’ve complied a list of commonly used roof drain and replacement part terminology, along with descriptions of each and commonly used nicknames. While not a complete list, this should help make sure you are speaking the same language as your sales contact.

Bolt-to-Bolt: The distance from one bolt (or lug) to the next, typically in inches. On a 4-bolt drain ring, it is measured using the bolts directly across the ring from each other, whereas on a 3- or 5-bolt ring the distance is measured from one bolt to the next going around the ring.

Selecting the Right 240V Plug Type for Roofing Tools

Posted by Hy-Tech Roof

Recently, a VARIMAT V2 customer came to us because his welder had shorted out and would no longer turn on. We quickly found the cause of the issue. The plug that connects to the machine’s power cord was changed from the 3-pronged 240V Leviton Wetguard plug we installed on the machine before it was sold to a clamp plug.

Clamp plugs attach by tightening two brackets down on opposite sides of a cord. When this happens, plastic fins on both brackets crimp the power cord, restricting the amount of electricity that can flow through (see right). This leads to a power back-up within the machine, which can melt compontents, catch wiring on fire, and short-out circuit boards.

Personal Fall Arrest Anchor Points: How to Ensure OSHA Compliance

Posted by Hy-Tech Roof

Fall arrest equipment prevents a worker from hitting the ground if they fall over the roof edge. According to OSHA regulations, workers 6 ft. or more off the ground must be tied off to a fall arrest system if there are no guardrails or safety net systems in place.

Having a fall arrest system prevents fall-related fatalities and injuries. Falls on average kill between 150 to 200 people every year.

A fall arrest system consists of a lifeline and shock-absorbing lanyard connected to a harness. The other end of the lifeline is then connected to an anchor (or tie-off) point. This anchor point offers the resistance necessary to stop a worker’s fall. 

In this post, we’ll provide details on OSHA’s anchor point regulations, and recommend how to ensure the anchor points your contractors select meet or exceed these requirements.
