Technical Specifications
Color/Coating Black powder coat over hot dip zinc
Material Formed/Welded sheet steel
Post Size 3.5” to 4” (89mm to 100mm)
Dimensions Base: 5/8” H x 5” W x 5” L (16mm x 128mm x128mm)
Tube: 3.5″h x 1.25″ dia (89mm x 32mm)
Inner holes: 0.40″ dia, 2″ o.c. (50mm)
Outer holes: 0.31″ dia, 2.0625″ o.c. (51mm)
Weight 2.35 lbs
Fasteners For residential engineering guidelines use (4) 3/8”x5 hex head lag screws, minimum (6) #14×3 or 1/4×3” deck screws or hex head lag screws.
Includes: (4) 3/8″x5″ lag screws, (8) #14×3″ black screws (ACQ compatible)
Recommended Uses Residential deck railing 36”-42” high, pergola or gazebo posts, support posts.
Composite Decking Composite or vinyl post sleeves may be used to cover posts.  However post skirts from different manufacturers vary in size and not all will fit over the post anchor.  Please ensure the post skirt you are using has an inside cavity clearance for 5″x5″x5/8″.

The 4×4 post skirts may be used with 4″x4″ post sleeves such as by placing the post skirt over the base of the post anchor and then sliding the post sleeve over the post so it sits flush on the flat shoulder of the post skirt.

Recommended Wood Species For best performance and ease of installation use with species ranging from cedar, spruce, redwood, pine, hem-fir with moisture content (m.c.) of 12%-20%.  To comply with residential engineering guidelines, do not use any species with specific gravity (density) less than the lowest of the above recommended species.
Other Species Douglas fir – ensure cutting edge of tube is sharp and m.c. not less than 12%.  Otherwise, install as if hardwood.
Hardwoods Requires hole saw and forstner bit installation technique as tube can not be impaled into wood easily.
Pre-Drilling For best performance it is recommended to pre-drill lag screw holes.
Concrete Surfaces Use minimum of 4 GRK Caliburn or Tapcon ¼” screws at least 2-1/4” long.
Sold separately.
