A cable groove is formed in the body member to receive a cable. The keeper has a lower surface to engage the cable received in the cable groove. A threaded fastener connects the keeper to the body member. A recess is formed in the body member to receive a washer on the fastener. ## Claims ### Claim 1 A clamp assembly, comprising: a body member; a cable groove formed in said body member to receive a cable; a keeper having a lower surface adapted to engage the cable received in said cable groove; a fastener opening formed in said body member having an open front end and a closed back end; and a recess formed in said body member at least partially surrounding said fastener opening, said recess being at least partially bordered by a first end wall, a second end wall, and a center wall extending across said fastener opening proximate said front end. ### Claim 2 (depends on 1) The clamp assembly of claim 1, wherein a fastener connects said keeper to said body member and a biasing member is disposed on said fastener between said keeper and said body member. ### Claim 3 (depends on 1) The clamp assembly of claim 1, wherein said cable groove has a bend of approximately 90 degrees. ### Claim 4 (depends on 1) The clamp assembly of claim 1, wherein said center wall includes a curvilinear inner side surface. ### Claim 5 (depends on 1) The clamp assembly of claim 1, wherein said first end wall includes an inner side surface that extends from the center wall at an oblique angle. ### Claim 6 (depends on 1) The clamp assembly of claim 1, wherein said second end wall includes a curvilinear inner side surface that extends from the center wall at a first portion. ### Claim 7 (depends on 6) The clamp assembly of claim 6, wherein said second end wall includes a linear inner side surface that is obliquely angled to the center wall at a second portion. ### Claim 8 (depends on 1) The clamp assembly of claim 1, wherein a top edge of said center wall connects to said first end wall by a first curved transition and to said second end wall by a second curved transition. ### Claim 9 A clamp assembly, comprising: a body member; a cable groove formed in said body member to receive a cable; a keeper having a lower surface adapted to engage the cable received in said cable groove; a fastener opening formed in said body member having a substantially U-shaped slot with an open front end; and a recess in said body member at least partially surrounding said fastener opening, said recess being at least partially bordered by a first end wall, a second end wall, and a center wall connecting said first end wall and said second end wall and positioned proximate said front end. ### Claim 10 (depends on 9) The clamp assembly of claim 9, wherein said cable groove has a bend of approximately 90 degrees. ### Claim 11 (depends on 9) The clamp assembly of claim 9, wherein a fastener connects said keeper to said body member. ### Claim 12 (depends on 9) The clamp assembly of claim 9, wherein a top edge of said center wall extends above at least one of the first and second end walls. ### Claim 13 (depends on 9) The clamp assembly of claim 9, wherein a bottom edge of said center wall is spaced above the recessed area. ### Claim 14 (depends on 9) The clamp assembly of claim 9, wherein said fastener opening includes a first angled side and a second angled side that widen the fastener opening from the U-shaped portion. ### Claim 15 (depends on 9) The clamp assembly of claim 9, wherein said center wall includes a curvilinear inner side surface, said first end wall includes an inner side surface that extends from the center wall at an oblique angle, said second end wall includes a curvilinear inner side surface that extends from the center wall at a first portion, said second end wall includes a linear inner side surface that is obliquely angled to the center wall at a second portion. ### Claim 16 A clamp assembly, comprising: a body member; a cable groove formed in said body member to receive a cable; a keeper having a lower surface adapted to engage the cable received in said cable groove; a fastener opening formed in said body member having a substantially U-shaped slot with an open front end; a fastener extending through the fastener opening and connecting said keeper to said body member; a biasing member disposed on said fastener between said keeper and said body member; a recess in said body member at least partially surrounding said fastener opening; a first end wall bordering the recess; a second end wall bordering the recess; and a center wall connecting said first end wall and said second end wall and positioned proximate said front end. ### Claim 17 (depends on 16) The clamp assembly of claim 16, wherein said cable groove has a bend of approximately 90 degrees. ### Claim 18 (depends on 16) The clamp assembly of claim 16, wherein said center wall includes a curvilinear inner side surface, said first end wall includes an inner side surface that extends from the center wall at an oblique angle, said second end wall includes a curvilinear inner side surface that extends from the center wall at a first portion, said second end wall includes a linear inner side surface that is obliquely angled to the center wall at a second portion. ### Claim 19 (depends on 18) The clamp assembly of claim 18, wherein a top edge of said center wall extends above at least one of the first and second end walls and a bottom edge of said center wall is spaced above a plane containing the recessed area.
