Can ICON AL38DQ Cast Coupler Lock Work On Rolled Lip Coupler ?  

Published 09/10/2025

Question:

Can I use the AL38DQ cast-style lock on a rolled-lip coupler, or do I need a different ICON model?

Dale, the Cast Style Lock # AL38DQ is only for cast housings -if you’ve got a rolled-lip coupler, it may work, but it depends on what you mean exactly by rolled lip. Some cast couplers do have a little bit of a rolled lip, such as the bulldog # 3370091562. If your coupler lip is actually long and flat like # DM13203-52 then you'd instead want the Flat Lip Lock # AL63DQ.

Do you know if your coupler is flat-fronted or more rounded?
