* Refer to the Simpson Strong-Tie anchor product range for suitable anchors. Typical anchor solutions are SET-XP and AT-HP, depending on the concrete type, spacing and edge distances.

** The published characteristic capacity is based on medium term load duration and service class 3 according to EC5 (EN 1995). For other load duration and service class, please refer to the ETA to get more accurate capacities

Installation

The posts must have a slot to suit the vertical metal plate and 2 holes for the Ø12mm dowels.

Installation

Timber install

Make a vertical notch in the base of the post
Mark out & drill dowel positions
Drill holes through the post with 12mm dia. Bits
Position the post on the post base & insert pins

Fixings

Fixing Installation to Concrete

Mechanical Fixing

SST Recommended Fixings: FM753 3DG – M16x145 (code 75320c1614500)

Recommended Concrete Pad Size: 450mm Wide x 450mm Long x 350mm Deep (see illustration below)

Recommended Concrete Grade: C25 (mixing ratio of 1:1.5:3 (Cement:Sharp Sand:Aggregate) with typically 0.5 water-cement ratio)

Installation Instructions:

Position the post-base centrally on the concrete pad.
Identify and mark out the position for the anchors.
Drill holes perpendicular to the concrete surface, Ø16 x 115mm deep.
Clean the dust from the holes 3 times using a brush, pump or vacuum. This is a crucial step.
Reposition the post base and insert the anchors (tap gently with a hammer if needed) and use a torque wrench to tighten to the recommended installation torque of 100Nm

Resin Fixing

SST Recommended Fixings: LMAS M16x170 (code LMAS1618130020)

SST Recommended Resin: ATHP

Recommended Concrete Pad Size: 450mm Wide x 450mm Long x 350mm Deep (see illustration below)

Recommended Concrete Grade: C25 (mixing ratio of 1:1.5:3 (Cement:Sharp Sand:Aggregate) with typically 0.5 water-cement ratio)

Installation Instructions:

Position the post-base centrally on the concrete pad.
Identify and mark out the position for the anchors.
Drill holes perpendicular to the concrete surface, Ø18 x 130mm deep.
Clean the dust from the holes 3 times using a brush, pump or vacuum. This is a crucial step.
Add Resin using dispenser and fill the hole half-way
Remove nut and washer from anchors, then Insert the anchors carefully into the holes
Once resin has hardened (check for a change in colour) reposition the post base over the top of the anchors, after carefully cleaning excess resin from the area
Use a torque wrench to tighten to the recommended installation torque of 100Nm

PLEASE NOTE – Anchor performance will only be valid when using Simpson AT-HP Resin
