SEISMIC ALUMINUM HEAVY-DUTY FLOORING
SYSTEM – RECESSED BLOCKOUT APPLICATION
MODEL(S): PTX/PTXw
PTX Floor to Floor System – 2” Through 12” Sizes
GENERAL DESCRIPTION
This Heavy-Duty Seismic Recessed System can
accommodate larger openings with multidirectional
movement requirements. An integral moisture
barrier keeps the weather out.
Introduction + Safety
Please read the complete instructions carefully before beginning any work. To ensure proper
installation and performance of the product, the following actions must be completed by the
installing contractor. Failure to do so will affect the product warranty.
Transportation + Storage
oInspect all shipments and materials for missing or damaged components and
hardware.
oMaterial must be stored in a clean, dry location.
Preparation
•Locate the packing slip(s) and/or shop drawings.
•Verify that all products listed on the packing slip are included in the package.
•Check the products for damage. If products are damaged, report a freight claim
immediately and leave the products in their packaging. If you sign for products
without reporting damage, you waive your right to a freight claim and will be
responsible for their replacement cost.
•Read the instructions thoroughly before beginning installation.
GENERAL SAFETY PRECAUTIONS
Improper selection, installation, or use can cause personal injury or property
damage. It is solely the responsibility of the user, through their own analysis, to select products suitable to the
specific application requirements, ensure proper maintenance and use as intended. Follow local, state, and
federal regulations for proper installation and operation requirements.

Tool List
•Tape measure
•Chop saw to cut product to length
•Electric drill with Ø1/8”, Ø5/16”, Ø5/32”
masonry bit & Ø3/8” metal bit
•Slotted drivers for anchors
•Rubber mallet
•Broom & dustpan or vacuum
•Level
•Masking tape
•Silicone sealant
•Structural epoxy or construction
adhesive
Included with the expansion joint system:
•Ø3/8” x 3.00” Lg. Wedge bolt screw
•Ø1/4-20 x 5/8” Lg. screw
•Ø3/16" x 1 3/4" Lg. Tapcon screws
Preinstallation
1. Pour floors with blockouts as shown on shop drawings. The blockout should be a
minimum of 2” wider than the exposed cover width by the specified depth.
2. Ensure the area where the expansion joint system is being installed (including the
blockout area) is smooth and level. High spots should be ground down and low spots
filled in. Make sure the substrate is clean by sweeping and/or vacuuming substrate .
INSTALLATION (EJN-PTX-400 THRU EJN-PTX-1200 ONLY)
1. After predrilling Ø3/8” clearance holes in the base member frames per the shop drawings,
position them in blockouts as shown below. Using the frame as a template, mark, and
drill Ø5/16” holes for the Ø3/8” wedge bolts. Do not fasten to the substrate yet, See
Figure 1.

2. Using Tape or other temporary methods, drape Moisture Barrier sheet into Joint Opening
and across each side. Care must be taken to provide enough slack in the joint opening so
the moisture barrier can “flex” during thermal and seismic movements. Minimal tape
should be used – just enough to hold the moisture barrier temporarily in place, as
supplied anchors will be used to hold base frames and moisture barrier in place. End of
sheet good should extend past 1st predrilled hole for proper anchoring. Note: if possible,
moisture barrier “gutter” should be installed to guide moisture to nearest drain tube or
side of building. A five-degree (5º) slope should be adequate to accomplish this. See
Figure 2
3. Set the base frames into position and attach with supplied wedge bolts through the
previously drilled holes. Before installing base member frames to the blockout opening
with supplied anchors, apply a bead of silicone sealant to the underside of the base
extrusion at the outside end of the extrusion. See Figure 3.

4. Install the wing plates to the base member frames with the Ø1/4-20” screws. Protect the
exposed surface of the expansion joint before installing, JointCrete™ (sold separately) in
the blockout, and making sure the filler is level with the surrounding substrate. See
Figure 4.
5. Lay the cover plate over the left base frame with ends flush and mark the cover plate
center holes onto the base frame near the inside edge using masking tape. Repeat this on
the right side. Position the centering bar mechanisms in the spring track on the base
frames and align with the marked locations. The centering bar mechanisms will be
diagonal to the opening. See Figure 5a. Tape may be needed to hold the spring assembly
in place. See Figure 5.

3. Using tape or other temporary methods, drape Moisture Barrier sheet into Joint Opening
and across and up wall side. Care must be taken to provide enough slack in the joint
opening so the moisture barrier can “flex” during thermal and seismic movements.
Minimal tape should be used – just enough to hold moisture barrier temporarily in place,
as supplied anchors/screws will be used to hold base frames and moisture barrier in

anchor hole. Note: if possible, moisture barrier “gutter” should be installed to guide
moisture to nearest drain tube or side of building. A five-degree (5º) slope should be
adequate to accomplish this. See Figure 14.
