Question:
Between the # AL38DQ cast and # AL63DQ flat-lip, which one is more universal?
asked by: Alan
Expert Reply:
Alan, it comes down to coupler geometry, not universality in the traditional sense. The # AL63DQ covers the flat-lip coupler crowd which is common on travel trailers, while the # AL38DQ secures the cast-style coupler crowd which is more common on equipment trailers, but these are not concrete and can be found on others as well. Both are equally secure - they share the patented fins that block angle grinders and the anti-drill core.
Which type of trailer are you trying to protect - RV or equipment hauler? You may want to send in a pic so we can figure out which style lock is best for you.
