Formwork Lock (Ciroz)
A formwork lock—called ciroz on site—clamps the ribbed tie through opposite form panels so concrete pressure does not open the form. Espada İskele offers 3 mm and 4 mm base plates in painted or galvanized finish. Quantity and delivery are confirmed in the quote; no fixed list price is published.

ESPADA İSKELE
What Is a Formwork Lock (Ciroz)?
A formwork lock holds opposite form panels against concrete pressure by clamping the threaded/ribbed tie that passes through the wall. On Turkish sites it is often called ciroz; the product name is formwork lock (kalıp kilidi).
Typical build: a base plate, a body that seats the bar, and a wedge or latch that tightens. Release is quick; correct storage and removing deformed pieces protect reuse life.
Espada İskele offers 3 mm or 4 mm base-plate thickness, painted or galvanized. The widely searched 3.5 mm is not in this stock set—choose between 3 mm (lighter) and 4 mm (higher pressure / wall forms). Quantity and delivery are confirmed in the quote; no fixed list price is published.
The same family also lists a ciroz / spring clamp tensioner as a separate accessory card: it tensions the spring lock on site and sits outside base-plate and finish filters.
Spring formwork lock
Base plate, spring and latch — clear in one piece
A body that seats the ribbed tie and a latch that tightens; 3 mm or 4 mm base plate, painted or galvanized. On site it’s called ciroz—the right pick is confirmed in the quote.
Formwork Lock (Ciroz) Varieties
Espada formwork locks are offered with a 3 mm or 4 mm base plate, painted or galvanized. Match thickness and finish to site load and exposure, then confirm the right combination in your quote.
3 mm and 4 mm base plate
3 mm suits lighter use and frequent cycles; unit weight is 380 g. 4 mm is often preferred for higher pour pressure or wall lines; unit weight is 420 g (same for painted and galvanized). This Espada set lists only these two thicknesses; 3.5 mm is mentioned as a mid-market search, not as stock.
Painted and galvanized finish
Painted finish is common for short–medium site circulation. Galvanized is considered when storage and rust risk call for longer protection. Confirm the finish with site conditions in the quote.
| Model | Base plate | Finish |
|---|---|---|
| 3 mm Painted Formwork Lock (Ciroz) | 3 mm | Painted |
| 3 mm Galvanized Formwork Lock (Ciroz) | 3 mm | Galvanized |
| 4 mm Painted Formwork Lock (Ciroz) | 4 mm | Painted |
| 4 mm Galvanized Formwork Lock (Ciroz) | 4 mm | Galvanized |
Base-plate size is often cited around ~70×105 mm in the market; clamp range is typically discussed for 6–10 mm ribbed bar. Packs of about 50 pcs are common trade practice—Espada confirms size, pack and stock in the quote; this page makes no capacity or price claim.

3 mm or 4 mm? Painted or galvanized?
Decide from pressure / cycles and storage—not from a price list alone.
Pressure and line type
Light / frequent cycles → consider 3 mm. Higher wall pressure → prioritize 4 mm.
Storage and rust
Open storage / long holds → galvanized. Short circulation → painted is enough on many sites.
Quantity and pack
Round quantities with the common ~50-pack culture; exact pack is written in the Espada quote.
Confirm in the quote
Send base mm, finish, quantity and delivery place. Plate band and clamp range are confirmed against stock.

What Is a Formwork Lock For?
A ciroz / formwork lock clamps panels on the tie so the form gap stays controlled during the pour.
Wall formwork
On opposite wall panels, ribbed tie + formwork lock limits panel separation under pressure.
Column formwork
Column cycles often need fast clamp–release; lock base and finish affect cycle speed.
Site care
Keep the wedge seat clean, segregate deformed pieces, and reduce rust risk in wet storage. Service life follows finish choice and care.

Frequently Asked Questions
Are ciroz and formwork lock the same?
Yes: ciroz is site slang; formwork lock is the product name. Espada uses both on this page.
Should I choose 3 mm or 4 mm?
Espada lists only 3 and 4 mm. 3 mm for lighter / frequent cycles; 4 mm often for higher pressure or walls—confirm with support if unsure.
Why is there no 3.5 mm?
3.5 mm is a common market search; this Espada filter set stocks 3 and 4 mm only. Searchers for 3.5 mm are directed to those two options—no fake stock claim.
Painted or galvanized?
Painted is often enough for short circulation and covered storage. Galvanized is considered for long holds or damp conditions.
How many per pack?
Packs of about 50 are common trade practice; Espada writes exact pack and quantity in the quote.
What is a ciroz / spring clamp tensioner? Same as the lock?
No. The ciroz / spring clamp tensioner is the tool that tensions the lock on site—not the lock itself. It appears as an accessory card in this family and is outside base/finish filters.
