WOCD Limiter

Last year at this time, I was working with a half dozen clients in my consulting practice. Ever since I started working on the River House full-time, I have dropped all but Formlabs where I have a one-day-per-month commitment. In some ways, that day feels like a vacation even though it is a very exhausting 10-hour day with the commute. That said, I enjoy the work a great deal because I get to use a part of my brain that does not get much of a workout in the shop. Today, one of the people I met with asked if I had any parts to print. He wanted to show off the new product he and his team have been working on. As it happens, I had a part designed for use as a building code-required safety device for one of the windows on the second floor of our new house. I am not at liberty to disclose any attributes of the new product but I can tell you it includes some very exciting capabilities.

A Window Opening Control Device (WOCD) is required on any operable window with a sill lower than 24″ from the floor and an outside drop greater than 72″. We have one such window and the limiter must prevent it from opening more than 4″ unless a 2-stage release is activated to allow for egress in the event of fire.
