Abstract
According to one embodiment, a cable anchor system for an end terminal includes a cable anchor bracket configured to couple to a guardrail, in which the cable anchor bracket includes a flat plate having an aperture formed therein and a plurality of protrusions extending from a plane containing the aperture. The protrusions are configured to releasably engage the guardrail.
Claims16
A guardrail system, comprising:
- a guardrail;
- an end terminal coupled to the guardrail;
- a support post for supporting the end terminal;
- a cable anchor bracket coupled to the guardrail;
- a cable extending between the support post and the cable anchor bracket;
- the cable anchor bracket comprising:
- a plate having an aperture formed therein;
- a plurality of protrusions coupled to the plate and extending from a plane containing the aperture, the plurality of protrusions releasably engaging a plurality of apertures formed in the guardrail;
- wherein the cable is coupled to the support post at a first end and coupled to the aperture of the plate at a second end, the cable terminating at the aperture such that an extension of a longitudinal axis of the cable from the second end forms an acute angle with respect to a longitudinal axis of the guardrail and approximately intersects a centroid of the protrusions;
- and
- wherein a longitudinal axis extending through the center of the aperture in a direction substantially perpendicular to the plane having the aperture is substantially perpendicular to the longitudinal axis of the cable when the cable is coupled to the plate having the aperture.

A guardrail system, comprising:
- a guardrail;
- an end terminal coupled to the guardrail;
- a support post for supporting the end terminal;
- a cable anchor bracket coupled to an attachment portion of the guardrail;
- a cable extending between the support post and the cable anchor bracket;
- the cable anchor bracket comprising:
- a flat plate defining a plane having an aperture formed therein;
- a plurality of protrusions coupled to the flat plate and extending from the plane containing the aperture, the plurality of protrusions releasably engaging a plurality of apertures formed in the attachment portion of the guardrail;
- and
- wherein the cable is coupled to the support post at a first end and coupled to the aperture of the flat plate at a second end, a longitudinal axis of the cable substantially aligning with the plane defined by the flat plate having the aperture formed therein.
