It is a friction fit instead of the screw nut type and attaches securely, even though there are no threads, locking mechanism or latch. The same applies to Ridgid Wet Dry Vacuums, it works perfectly with most of their models also.
The PVC hose is wrapped around a steel wire that can be grounded easily. This heavy duty PVC hose will not collapse under pressure from your dust collector plus the hose is clear allowing you to see directly inside to spot any kind of obstruction.
