CCQM/CCTQM/ECCLQM/CCCQM/ECCLQMD Column Caps for GFCMU and Concrete Piers
On This Page
Product Details
The CCQM/CCTQM/CCCQM/ECCLQM embedded column caps are designed for use in raised pier foundations and applications where heavy timbers rest on concrete or concrete block columns. The heavy-gauge beam seats and unique SSTB-style anchor bolts provide the high uplift and lateral resistance needed to help resist high-wind events. The ECCLQMD is a variation that incorporates an additional seat to support a third member at the corner connection. The CCCQM is a variation that incorporates a stirrup on each side for intermediate support beams perpendicular to the main channel.
Framing is fastened with Strong-Drive® SDS Heavy-Duty Connector screws (included) that install with no predrilling and feature a corrosion-resistant double-barrier coating.
CCQM — intended for use along a floor support beam and non-corner locations
CCTQM — also for use along a floor support beam and non-corner locations with a side stirrup that accommodates intermediate support beams coming at 90°
CCCQM — for use along a floor support beam with a stirrup on each side of the main channel that accommodates intermediate support beams coming at 90°
ECCLQM-KT — intended for use at the corners with MSTQM straps to make the connection from the ECCLQM to the wall framing above
ECCLL/RQMD-KT — ideal for applications where a member is needed off the corner of the structure, such as a deck joist/beam
Material
- Column caps — 7 gauge; strap (MSTQM) — 12 gauge
Finish
- Column caps — hot-dip galvanized or Simpson Strong-Tie gray paint; strap (MSTQM) — galvanized (ZMAX®)
Installation
- Use all specified fasteners; see General Notes
- Reference Options for Column Caps for Concrete-Filled Pilasters, Grout-Filled CMU or Concrete Piers (T-C-CCQM-WS) special order worksheet for ordering assistance
Options
- For variable widths on side stirrups specify W3 or W4 (3 1/4" to 7 1/8") and add an "X" to the end of the core model name. Example: CCTQM5.50X-SDSG, W3 = 3 5/8".

Load Tables
These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.
- Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
- Total uplift load and lateral load is based on tested anchor failure in the pier.
- Allowable loads are based on either a 16" square grout-filled CMU pier with f'm of 1,500 psi or a 16" square CMU shell filled with 3,000 psi concrete. A minimum of (4) #7 vertical rebars are required. The Designer shall design and detail the GFCMU/concrete pier to resist all forces including uplift, shear and moment.
- Pier height per Designer.
- Side beam and main beam uplift loads assume DF/SP members and are not additive.
- The allowable loads listed for grout-filled CMU apply to solid concrete piers of 2,500 psi concrete a minimum of 16" square.
- The allowable loads listed for CMU shell-filled with 3,000 psi concrete apply to solid concrete piers of 3,000 psi concrete a minimum of 14" square.
- The ECCLQM-KT is a kit packaged with (2) MSTQM straps and (32) 1/4" x 2 1/2" Strong-Drive® SDS Heavy-Duty Connector screws. One strap may be installed on each face of the ECCLQM, using the SDS Heavy-Duty Connector screws in the beams and (26) 0.162" x 2 1/2" nails (not provided) in the wall framing. The MSTQM strap's allowable tension load is 6,240 lb. If straps are not installed, table uplift applies to beam only.
- Any side stirrup not fully supported by grout- or concrete-filled CMU has an allowable download of 7,000 lb.
