EPS4Z Column Bases

061a-2015

The EPS4Z provides a light-duty connector for attachment of posts to concrete.

Material: 14 gauge

Finish: ZMAX® coating; see Corrosion Information.

Installation:

  • Use all specified fasteners. See General Notes.
  • Post bases do not provide adequate resistance to prevent members from rotating about the base and therefore are not recommended for non top-supported installations (such as fences or unbraced carports).
  • Embed into wet concrete up to the embedment line. A 2″ minimum side cover is required to obtain the full load.
  • Posts shall be preservative-treated wood to meet building code requirements.
  1. Loads may not be increased for short-term loading.
  2. Concrete shall have a minimum compressive strength, f’c = 2500 psi.
  3. Multiply Seismic and Wind ASD load values by 1.4 or 1.6 respectively to obtain LRFD capacities.
  4. In accordance with IBC Section 1613.1, detached one- and two-family dwellings in Seismic Design Category (SDC) C may use “Wind and SDC A&B” allowable loads.
  5. Download shall be reduced where limited by the design capacity of the post. See Post Capacities for common post allowable loads.
  6. For lateral loads: F1 allowable = 575 lbs. and F2 allowable = 680 lbs.
  7. Designer is responsible for concrete design.
  8. Structural composite lumber columns have sides that either show the wide face or the edges of the lumber strands/veneers known as the narrow face. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for load reductions due to narrow face installations.
  9. NAILS: 10dx1 1/2= 0.148″ dia. x 1 1/2″ long. See other nail sizes and information.
