Adjustable Chairs
Standard screed chairs and pipe holders are available sizes ranging for a 3-3/4" slab to 13" slab. These chairs have the "butterfly" leg design for added strength, and yet this chair can be placed over and beside rebars for easiest screed pipe alignment. The table below shows the range of adjustment (minimum and maximum slabs) for each size chair and pipe holder. Place screed chairs at 4'-0" maximum under screed pipe. On special order, chairs can be made with galvanized wire, electro-galvanized, or provided with stainless dowels between wire and form face. Stock pipe holders are made for 1" ID pipe.
WARNING: Do not use to support the weight of finishing (screed) machines.
NOTE: Height based on 1" ID pipe.

Heavy Duty Chairs
Heavy duty screed chairs and pipe holders are available sizes ranging for a 4-3/8" slab to 16-7/8" slab. The table shows the range of adjustment (minimum and maximum slabs) for each size chair and pipe holder. Place screed chairs at 2'-0" maximum under screed pipe. On special order, chairs can be made with galvanized wire, electro-galvanized, or provided with stainless dowels between wire and form face. Stock pipe holders are made for 1-1/4 and 1-1/2" ID pipe. SWL is 800 lbs.
NOTE: To obtain actual slab limitations, you must add pipe O.D. to above dimensions.

MegaScreed™ - Plastic
Determine the finished elevation of concrete with a laser or string line and position a #4 rebar stake on the subgrade at the strikeoff point. Place the MegaScreed Driver over the rebar and strike with a Dead Blow Hammer until the height marker aligns with the laser or string line. Remove the Driver and place the high strength Yoke over the rebar. The Yoke will maintain the exact position indicated by the height marker. Repeat this procedure as necessary at each screed location. Then set a 1-1/2" ID, 2" OD schedule 40 screed pipe on top of Yokes and you are ready to pour. 100 per package.

Pinhead - Metal
Several locations can be set at the same time. #4 rebar stakes are driven in line, about 5 feet apart, about floor grade. Each stake is then shot and driven to elevation of 1-13/16" below finished floor grade. Pinheads rest on these stakes and provide a saddle for the temporary screed pipe. A 1-1/4" ID pipe will slide forward with each mixer load, leaving the Pinheads free to remove and reuse. 100 pieces per carton.

Application
The location of the joint should be screeded and floated before installing Zip Strip.
With a straight edge guide, groove out a slot to the desired depth. The depth should be equal to the depth of the Zip Strip and at least a fourth of the thickness of the slab. Groove the slot well to part any aggregate that might block insertion of the Zip Strip.
Press Zip Strip down into the formed groove so that the removable top is level with the surface of the concrete.
Finish by pulling the top section off to leave the joint former firmly embedded in the concrete.
Trowel and finish off concrete.

Combiform Rail
Combiform screed rail and form is used in the production of flat slabs. The Combiform screed rail is manufactured from plain sheet metal and a strip of polyethylene plastic. Available in 7.2' lengths in various heights up to 5-3/4" (125mm). Combiform functions both as a form and a screed rail on any type of prepared base. Being a stay-in place form, the Combiform will help to control shrinkage cracks which will occur along the plastic strip. The Combiform screed rail is machine made to close tolerances. The side of the rail is perforated to allow easy concrete flow and pass through of reinforcing steel up to 7/8" (22mm) in diameter, depending on size. For installation grade pies are placed on each end and 3' centers. Combiform is set to grade leaving 1-1/2" gap underneath to allow concrete to fill void (when initially setting, keep concrete cover to maximum 1/2" above combiform flange). When pouring slab vibration along edge is recommended to fill void. For more installation techniques call Masons.
