CONCEALoc Hidden Fastener

Important Information

CONCEALoc Hidden Fasteners were designed exclusively to install TimberTech grooved and square shouldered planks.

  • In areas with obstructed airflow such as roofs and on-grade applications, a minimum of 1½" is required.
  • Sleeper system must be supported by and connected to the substructure over which the deck is built.

TimberTech INSTALL THE FIRST PLANK
  • Pre-drill with 5/32" drill bit and fasten outer edge of first plank at each framing support 1" from the edge using TOPLoc or a #8 x 2½" stainless steel or other high-quality coated deck screw. For a complete fastener-free surface, Cortex can be used on first and last boards.
  • For further instructions on Cortex, please refer to the instructions in the package.

TimberTech POSITION CONCEALoc FASTENERS
  • Fully insert the CONCEALoc fastener into grooved edge of plank. Screw hole should be lined up with the center support joist.

TimberTech INSTALL CONCEALoc FASTENERS
  • Install provided screw at 45° angle through the fastener and into the joist while applying pressure on the fastener.
  • Install one fastener and one screw at each joist.
  • Make sure fastener is in full contact with edge of plank and the screw is holding the fastener down tight to the deck board.

TimberTech COMPLETE INSTALLATION
  • Place the next plank into position against the fasteners. Slightly raise the outer edge of the plank being installed and slide it onto the fastener until the plank contacts the spacer tab. When properly installed the inserted plank should be in contact with the bent-forward spacer tab at the left end of the clip. To achieve this use a scrap piece of decking at least 24" in length and use it as a tamping block to drive the plank further into the clip and the screw will fully engage the plank to the spacer tab if not already in contact. Do not use hammer or damage to the edge of the plank may occur.
  • The last plank will need to have the outside edge attached using the method described in Step #1. It may be necessary to rip the last plank to fit.

TimberTech HOW TO INSTALL AT BUTT JOINTS
Joists at butt joints must be doubled up for proper installation
  • Install fasteners as detailed below. Note that two clips on the right are shifted approximately ¼" to the right of center of joists. If this is not done the spacer tab may fall within the gap of the butt joist.

TimberTech HOW TO INSTALL ON DIAGONAL
  • When the deck is located in a corner of the house, start with small triangular piece of decking in the corner and work your way out.
  • Offset the center ½" towards the long point of the joist, so screw will not exit the side of the joist when driven.

TimberTech HOW TO REPLACE A PLANK
  • Make two parallel cuts down the center of the board to be replaced, then remove the center piece.
  • Using a small pry bar, remove the remaining pieces of decking from the tabs.
  • Using a reciprocating saw, remove the tabs on the side of the board with the screw heads showing.
  • Position new board into place, and carefully drive onto remaining tabs.
  • Once the board is set into position, secure the loose edges with Cortex, stainless steel or high-quality coated deck screws.

TimberTech HOW TO USE CONCEALoc WITH SQUARE SHOULDERED PLANKS
  • Create a 2" long groove on the edge of the plank at every joist.
  • Use TimberTech's CONCEALoc Groove Cutting Router Bit or a Freud model #56-112 or Bosch model #85610M ¼" slot cutting bit.
  • Flip the plank over and start the groove 3/8" off the bottom of the plank.
  • Set the depth of the cut from 7/16" to 1/2" deep.

Note: Be sure to ID the side of the plank that has the directional notch;
the planks with IDs should be installed to the same side. See Directional Notch
