The taymac large outdoor outlet box is satisfactory and appropriate and fits well with your regular usage. It is just a cover that will go over an existing basic junction box that is in the wall. It comes with a bunch of device adapter plates, one of which has a round opening with removeable "sizes" molded into it. It allows two different connections that have to be very high off the outlet. This box is deep enough so that your cords can bend without pinching the plug. It is designed for exterior outlets and should be rain proof.

It comes with adapter plates for many different configurations including single left, right or center. It is easy to install, no breakage when punching out the cord slots, opens and shuts easily.

Why We Like This:
  • You can install any combination of outlets and switches
  • Works great for any plug that has to be piggy backed
  • Includes new cover plate with insulation to weatherproof it
  • Plenty of room to close cover with multiple cords plugged in

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate box. The sealproof receptacle cover is exactly that - it's a simple box that hits all the right notes. The Screws that comes with your GFCI Outlet are the same screws that you would use to secure the box and the GFCI to the wall. It is easy to install even on concrete. It is great for applications in multiple configurations.

The Building Block Style Adapter together with Pre-installed Adhesive Gasket makes installation a clean and easy job. It is easy to open (use a thump to push up) with a reinforced hinge that withstands a 40 lb stress test. It is allows for multiple heights by swinging the bar to an up or down position. It is also easy to install. The screws that come with your GFCI Outlet are the same screws that you would use to secure the box and the GFCI to the wall.

Taymac Outdoor Outlet Cover

We would, of course, be remiss if we didn't mention taymac outdoor outlet cover for regular usage. It is easy to setup as a one gang outlet cover. The usual size on its mounting plate is almost 2-1/2 in wide. It keeps the water out while the receptacle is being used. The cover has provisions for drop cords at the bottom and there is enough room to allow you to run the conduit to the utility box the cover is attached to. It is 4-9/16" at the opening with a slight taper to the back of the box. This gives more depth to ensure the cord cap can be plugged in and the cover will close.

This cover has plenty of room. There are lots of screw hole placement options too.

Why We Like This:
  • Large box, well made and versatile
  • More cords going under the garage doors
  • Attaches to the face of the out door box
