I use, under recommendation from a long time audio dealer, the Hubbell HBL5262 outlet. This is the 15A version. He insists that unless you are truly using 20 plugs, that this version will provide better electrical contact to the 15A plug blades.Depends on which Series Hubbell HBL5262 duplex receptacle you purchase.

The Dealer maybe correct if the duplex receptacle is the Hubbell HBL5262 Extra Heavy Duty Industrial Series.
See page 6.
The Hubbell HBL5262 Compact Extra Heavy Duty Industrial Series duplex receptacle has the neutral "T" type contact configuration.
See page 10.
The HBL "Compact" Extra Heavy Duty Industrial series has a thinner body than the HBL Extra Heavy Duty Industrial Series. Also note the 2 white block areas on the face of the receptacle for panel and circuit identification info.
How do you know for sure which one you have?
With a pen light look inside the neutral slot, (longer of the two), of the receptacle face plate at the contact.
Does it look like the picture on page 6 or the picture on page 10?
