Product Notes
#### Concrete Formwork (book)
This trade paperback from Leonard Koel is the only non-hardware item here, priced at $20.36. It gives you 282 pages and an ISBN for the Concrete Formwork title, making it a useful starting point if you want to understand formwork concepts before you spend on hardware. The Good-condition designation means the spine and cover already show wear, and pages may include notes, highlighting, or previous owner labels. If you expect a shelf-perfect reference, this listing is not that, but as a working copy it keeps the entry cost low.
#### Sandbaggy Round Head Aluminum Form Pin (Reusable)
At $297.00, this Sandbaggy round head form pin is the biggest single outlay in the group, but it comes as a 500-unit quantity. The tapered pin has a 15/16\" round head, a 1-inch slot opening, and a heat-treated finish, and the product description emphasizes easy insertion and removal. Because the pins are reusable, the per-use cost can make sense for ongoing formwork. For a one-time small pour, though, the upfront price is hard to justify.
#### Sandbaggy Galvanized Steel Snap Tie Wedges (2 ⅜\" x 6 ⅛\")
Priced at $37.03, this is a 10-pack of Sandbaggy snap tie wedges measuring 2 3/8\" x 6 1/8\". The listing describes 11-gauge hot-dip galvanized steel, a 0.45 lb weight, and a rating up to 3,250 lbs, plus compatibility with standard and heavy-duty snap ties and double 2x4 walers. The main limitation is the count: ten wedges lock up a modest amount of wall, so plan to buy multiple packs for larger formwork.
#### Sandbaggy Heavy Duty Pencil Rod Clamp (w/ Bolt)
This clamp is priced at $6.00, the lowest listed price in the set. It is made of cast malleable iron, includes a bolt, and has three nail holes. Safe working load is listed at 1,125 lbs for 1/4-inch rods and 2,250 lbs for 3/8-inch rods, while the description says it works with smooth or deformed rods and suits battered or curved walls. Since it is a single clamp, your total depends on how many rod points you need to secure.
Final Recommendation by Use Case
- For a printed background on formwork and temporary works: pick the Concrete Formwork book. It is the only printed reference in this selection.
- For high-volume pinning on a large pour: the Sandbaggy Round Head Aluminum Form Pin 500-pack lines up with jobs that expect reusable pins.
- For standard snap tie walls: the Sandbaggy Galvanized Steel Snap Tie Wedges 10-pack gives you ten heavy-duty wedges to lock ties.
- For one-off rod clamping around curved or battered forms: the Sandbaggy Heavy Duty Pencil Rod Clamp is a simple single-clamp buy.
