10.5x5.3x4 Inch Medium Waterproof Electrical Connection Box - IP54 Rated Outdoor Extension Cord Enclosure for Timer Outlets, Holiday Lights & Cable Protection | Weatherproof Solution for Patio, Garden & Christmas Decorations

This rugged weatherproof electrical connections box is very sturdy, and has rubber seals at all openings to protect against the elements. The top clamps on securely. Each cord opening has half of a rubber grommet on the top lid, and the other half on the bottom box so that when you close it, a tight seal is made. The grommet has multiple segments to grip and form around various size and shape of cords. There is a removable strain relief for each cord to help help prevent it from slipping out. Very nice overall.
