Claims
- 1. A wire protection grommet for installation in a wire pull opening of a cellular raceway, the wire protection grommet comprising:
a housing configured for mounting in the wire pull opening, the housing defining a passage which extends through the wire pull opening when the housing is mounted in the in the wire pull opening, the passage being sized such that a plurality of wires can be passed freely through said passage, and the passage having a convex surface of a predetermined radius, which functions as a wire pull strain relief for wires that pass through the opening.
- 2. A wire protection grommet as set forth in claim 1, wherein the grommet is configured to lockingly engage into the wire pull opening.
- 3. A wire protection grommet as set forth in claim 1, wherein the grommet is configured for installation in an oval-shaped wire pull opening.
- 4. A wire protection grommet as set forth in claim 1, wherein the grommet is configured to be mounted in wire pull openings of varying sizes.
- 5. A wire protection grommet as set forth in claim 1, wherein the convex surface has a radius of at least one inch.
- 6. A wire protection grommet as set forth in claim 1, wherein the grommet formed of plastic.
- 7. A wire pull strain relief as set forth in claim 1, wherein the wire pull opening extends between a cellular raceway and a preset housing.
- 8. A wire protection grommet for installation in a wire pull opening to cell of a cellular raceway, the grommet comprising:
a proximal portion configured to be on the exterior of the cell of the cellular raceway, adjacent to the wire pull opening; a distal portion sized for insertion through the wire pull opening and into the cell of the cellular raceway; and the proximal and distal portions defining a central passage which extends through the wire pull opening when the grommet is installed in the wire pull opening, the central passage being sized such that a plurality of wires can be passed freely through said passage and including a radiused surface defining a wire pull strain relief to prevent wires that pass through the opening from being bent beyond a predetermined bend radius.
- 9. A wire protection grommet as set forth in claim 8, wherein the grommet is configured for insertion into a wire pull opening which extends between an preset and a cell of the cellular raceway.
