Poly / Resin Poly-Classic Capital Installation Instructions
Our new expanded line of Ornamental Capitals for Poly-Classic columns has prompted us to include more installation instructions to assist customers in deciding how they want to design their columns , as well as help in the actual final installation .
This page deals with capitals chosen from page 8 only : the Option One capitals . These are made of either Poly / Resin or Composite Plaster . Poly / Resin caps have a plug built-in to connect to the column shaft , and the capital itself carries the load of the overhead structure . For Composite Plaster caps without the built-in plug , the plug is a separate FRP piece that connects to the shaft , and the capital slides over the plug , so the plug carries the load instead of the cap .
For POLY-RESIN caps , the top of the shaft MUST be cut off before installing the capital , unlike the Option Two caps ( pages 11- 12 ). For simplicity , most installers choose to trim the shaft flush at the top of the neck ring molded in the shaft . For architecturally correct installations , if the capital is Roman Ionic , Greek Erectheum or Scamozzi , the installer may choose to trim the shaft at the top of the flat ring ( fillet ) directly below the neck ring . ( Pricing tables on page 8 show the height adjustment of the assembled column based on the simpler trimming at the neck ring . For architecturally trimmed columns , the overall height of the column would be reduced by the thickness of the neck ring that is being removed .)
TRIMMING shafts for use with POLY / RESIN CAPS : POLY / RESIN CAPITAL WITH NECK SLEEVE :
FRP PLUG FOR COMPOSITE PLASTER CAPS :
DO NOT TRIM THE TOP OF THE SHAFT if you are using a COMPOSITE capital . The plug attaches to the neck of the column shaft , and will be too short if the shaft is trimmed .
The sleeve of the cap or the plug should be screwed to the column shaft . For composite plaster caps , the cap should also be screwed to the plug . And the top of the caps should be screwed to the ceiling / soffit .
Plug ( similar to above ) will be attached to shaft neck to achieve total height required Sh aft . Plug m + uneck st bmust e be trimmed to 1 / t8 r" im taller mthan e dcapital t o 1 so / plug 8 " + neck will carry

cap load .
When attaching Poly / Resin caps or the FRP plugs to the shaft , or attaching the caps to the ceiling / soffit or plug , always pre-drill and countersink holes , and use screws that won ' t rust .
