This AC WORKS® brand locking adapter [ADL1420L1430], is very durable.  This locking adapter is NEMA L14-20P to NEMA L14-30R.  The NEMA L14-20P is a 20 Amp, 125/250 Volt, 4-prong male plug.  The NEMA L14-30R is a 30 Amp, 125/250 Volt, 4-prong locking female connector. The product has a maximum operating power of 5000 Watts and is backed by a 5-year limited warranty.  This locking adapter is typically used for generator/industrial/construction power solutions.  

With the new product design, we have added a power indicator light going around the entire product so you will always know when you are receiving power.  The bulky design was updated so the adapter will better fit into the inlet you have and a better grip, so no more getting stuck.
