The Board Compression Tool 400 mm straightens and clamps decking boards while they are being fixed. Timber boards are rarely perfectly straight; this tool pulls a bowed board into line against the previously fixed board, holds it there, and leaves both hands free to drive the screws.
It is made from stainless steel with a lightweight ergonomic handle, and has a working capacity of 400 mm.
Key features
- Straightens and clamps bowed boards while fastening.
- 400 mm capacity — compact reach for single-board correction and tight spaces.
- Stainless steel construction — will not rust on a wet site.
- Ergonomic, lightweight handle for repeated all-day use.
- Holds the board under pressure so both hands are free to fix.
- Keeps board gaps consistent along the whole run.
Where it is used
- Fixing bowed or twisted decking boards.
- Closing gaps on long board runs.
- Keeping spacing consistent across a large deck.
- Working alone, where a second pair of hands is not available.
Position the tool over the joist, take up the bow, check the gap with a spacer, then fix the board. Release and move along to the next joist.
