need to eliminate hortizonal space between bar and right end cap

Hi!

I would greatly appreciate someone specifically showing me which rule below I need to edit to fix get rid of the three pixel horizontal space between the right end cap and navigation bar on this page: http://www.topsecurityinc.com/ ?

.topnav-wrap *{margin:0;padding:0;}
.topnav-wrap{width:828px;margin-left:9px;height:42px;padding-left:5px;}
.topnav-wrap a{text-decoration:none;}
.topnav-wrap ul{list-style:none;}
.topnav-wrap p{margin:15px 0;}
.ts-2{border:medium none;border-collapse:collapse;overflow:hidden;text-align:left;width:859px;clear:both;}
.ts-2-1{border:none;float:left;height:42px;line-height:1px;margin-bottom:0;width:869px;padding:0;}

TIA
