The bracket comprises at least one each of a first type and a second type of mutually spaced fence member receiving channels (8a,8b,10a-10f), the or each channel of the second type (8a, 8b) having a greater width than the or each channel of the first type (10a-10f), as measured along a length of the bracket. The security barrier system comprises a plurality of support posts (4), attached to each support post is at least one bracket, the length of the bracket orientated vertically, and a plurality of fence members (12a-12h) orientated horizontally, each member passing through a corresponding one of the fence member receiving channels of each bracket. ## Claims ### Claim 1 A security barrier comprising: a plurality of support posts, and attached to a single face of each support post at least one elongated bracket comprising: mutually spaced fence member receiving channels comprising one channel of a second type and at least one channel of a first type aligned on each side of the one channel of the second type, the channel of the second type having a greater width than each channel of the first type, as measured along a length of the bracket, wherein each of the channels of the first type has a substantially semi-circular cross-section and wherein the channel of the second type has a linear central region between arcuate end regions; and a plurality of non-channel regions, the non-channel regions comprising an interconnecting region between each pair of adjacent channels, wherein the plurality of interconnecting regions lie in a common plane, the channels of the first and second types extending out of the common plane and parallel to the common plane, and wherein at least one of the interconnecting regions comprises an aperture, the aperture extending through the common plane and being configured to receive a fastener in a plane perpendicular to the common plane and a plane of the channels for securing the elongated bracket to the single face of the support post; a plurality of fence members orientated horizontally, each member of the plurality of fence members passing through a corresponding one of the fence member receiving channels of the at least one elongated bracket attached to each support post, wherein each fence member receiving channel of the first type has a width and depth approximately equal to a diameter of a corresponding fence member, and wherein the fence member receiving channel of the second type allows its respective fence member to slide upwardly along the support post and within the channel during an impact of a vehicle with the security barrier system. ### Claim 2 (depends on 1) The security barrier as claimed in claim 1, wherein the non-channel regions comprise a pair of end regions at ends of the bracket. ### Claim 3 (depends on 1) The security barrier as claimed in claim 1, wherein each of the interconnecting regions comprises an aperture. ### Claim 4 (depends on 1) The security barrier of claim 1, comprising three channels of the first type. ### Claim 5 (depends on 1) The security barrier as claimed in claim 1, wherein a channel nearest to a first end of the bracket is of the first type, and a channel second nearest to the first end of the bracket is of the second type. ### Claim 6 (depends on 1) The security barrier as claimed in claim 1, wherein each support post of the plurality of support posts has attached thereto two elongated brackets, the lengths of the elongated brackets orientated vertically. ### Claim 7 (depends on 6) The security barrier as claimed in claim 6, wherein the two elongated brackets attached to each support post of the plurality of support posts are identical to each other and attached to each support post of the plurality of support posts at a same position along a length of the support post. ### Claim 8 (depends on 7) The security barrier as claimed in claim 7, wherein at least one bolt attaches the two elongated brackets to each support post of the plurality of support posts, the at least one bolt extending through: an aperture of a non-channel region of a first of the two elongated brackets; an aperture of the support post; and an aperture of a non-channel region of a second of the two elongated brackets. ### Claim 9 (depends on 1) The security barrier as claimed in claim 1, wherein the support posts have substantially rectangular cross sections. ### Claim 10 (depends on 1) The security barrier as claimed in claim 1, wherein the non-channel regions of the elongated brackets are flush with the support posts. ### Claim 11 (depends on 1) The security barrier as claimed in claim 1, wherein each fence member of the plurality of fence members has a circular cross-section, the circular cross-section having a fence member diameter. ### Claim 12 (depends on 1) The security barrier of claim 1, wherein each channel of the fence member receiving channels of the second type has a depth substantially equal to the fence member diameter and a width greater than the fence member diameter. ### Claim 13 (depends on 1) The security barrier as claimed in claim 1 further comprising a single sheet of material bent to form the first type and second type of mutually spaced fence member receiving channels. ### Claim 14 (depends on 1) The security barrier as claimed in claim 1, wherein the aperture is located between a pair of adjacent channels.
