Twist and Seal Cord Dome 2 Pack

The Twist and Seal Cord Dome 2 Pack provides weather protection for multiple extension cord connections. It suits homeowners, RV owners and event organisers who run power strips, surge protectors or Y connectors outdoors. The domes keep connections dry during rain, sleet and ice. Each unit is constructed from commercial grade plastic with UV protection and is made in the USA.

Patented twist and seal design

The patented twist and seal mechanism lets you place connections inside the dome and secure them with a simple twisting motion. This seals out moisture and helps prevent tripped outlets while reducing the risk of electrical shock. The large interior measures 3.75 inches deep by 13 inches wide, accommodating bulky items such as power strips, Y connectors and 15 and 30 amp plug heads. Independent lab testing confirms the design meets and exceeds NEMA standards for protection against rain, sleet and ice.

Check connection count and cord gauge

Verify that the number and thickness of your cords fit within the 3.75 inch depth and 13 inch width before ordering. The dome is not suited for installations that require a sealed conduit or permanent hard-wired enclosure. Buyers who need protection for a single lightweight plug may find the interior space larger than necessary.

Questions about this item

How often should the UV-protected commercial-grade plastic dome be inspected or replaced after prolonged outdoor exposure?

The commercial-grade plastic with UV protection is built for heavy-duty outdoor use. Inspect the dome each season for cracks or seal wear; replace it if the twist-and-seal mechanism no longer closes tightly.

Will the 3.75-inch deep by 13-inch wide interior fit a 30-amp RV plug alongside a power strip without crowding?

The large interior dimensions of 3.75" deep x 13" wide are designed to accommodate bulky connections including 15 & 30 amp plug heads, power strips and Y connectors simultaneously.

Does the sealed dome trap heat from a loaded 15-amp power strip running continuously in direct sun?

The dome shields connections from rain, sleet and ice per NEMA standards; it is not ventilated, so a heavily loaded strip in full sun may run warmer than in open air.
