Around the sides of your mechanical dock leveler, gaps are created between the leveler and the concrete loading dock pit wall.
If these gaps are left uncovered they can become as large as a 14" by 14" (360 mm by 360 mm) hole in your wall and could cost $557 annually. (Based on a climate in Cincinnati, OH)
Installing energy efficient loading dock leveler weatherseals by Rite-Hite Aftermarket will close the gaps and will help reduce your heating and cooling costs. In many cases, these weatherseals will pay for themselves in four months or less.
