The BPH-4 Slotted-Base Post Holder is a patent pending re-invention of the classical optical post holder, combining a slim slotted base with a unique post holder. The top surface of the post holder has a series of kinematic indentations which, when used with the BPH-C-5 Post Collar, provide repeatable rotational alignment and indexing at 45° increments. The base features both angled and straight reference surfaces allowing edge-to-edge placement of adjacent post holders and, with the addition of the BPH-XB-5 Base Extender, can convert to a double-slotted base. The flat bottom also makes mounting more versatile and improves stability.

BPH-4开槽立杆支架是经典光学立杆支架的一项正在申请专利的再发明，它将一个细长开槽立杆与一个独特的立杆架结合在一起。顶部表面的持有人有一系列运动学刻痕,BPH-C-5邮报领一起使用时,提供可重复的旋转对齐,在45°增量索引。该基座具有角度和直的参考面，允许相邻柱架的边到边放置，并且，随着BPH-XB-5基座扩展器的加入，可以转换为双槽基座。平底也使安装更加通用，提高了稳定性。
