Does anyone know any place online that I can order a Carr Lane latch action toggle clamp from online? I found it at Grainger but they won't sell to individuals. Or can anyone point me towards another latch that will work well?

Order a grainger catalog. Or ask grainger to steer you in the direction of one of their resellars.

KBC tools sells De-Sta-Co toggle latches ..... the same if not beter than carr lane

Grainger wont sell to you? I buy from them all the time. Bought a 220v Fan motor for My A/C a few weeks back. That's screwed up. Now they always do slap a company name on there. I got the Lockheed discount last time :)
