Illyra JSL · Chicago tool company

Tools for the part of the job nobody designed for. 

We start on the jobsite, find the steps that still take two people or an improvised fix, and engineer them into something one person can do properly.

01Products

One trade. One task. Done right. 

We don't make another drill. Every Illyra JSL product is built around one specific, repeated task in one trade, and it has to earn its place in a tool bag that's already full.

02How we work

We ride along before we draw anything. Then we model the loads, build it in Chicago, and hand it to working pros. If it doesn't save real time on a paying job, it doesn't ship.
