Upholstery Hand Tools
Choose the staple family and leg length
Match the stapler first. Then choose a leg length for the material stack and the wood beneath it.
Read the tool’s exact model
The Arrow T50 uses its T50 family. The JT21CM and TT21 both use JT21 fine-wire staples. A fraction on the box is a length, so use the stapler’s model and staple family together when choosing a refill.
Account for the fabric fold
The amount of leg that reaches the wood depends on the thickness of the fabric and other layers it passes through. Compare a flat stretch of the cover with a folded corner. Arrow’s T50 manual also asks you to consider wood hardness when choosing a leg length.
Use the permitted lengths
The T50 manual lists six lengths, while Arrow’s JT21 chart lists three for the TT21 and JT21CM. Check the approved sizes for your model before assuming a longer refill in the same broad product family will feed through it.

If a T50 staple stands above the work, the maker recommends trying the next shorter approved length. Check the remaining thickness of the seat board as well, especially if its underside will stay exposed.
