USA Curling has announced its partnership with Brooms Up Curling Supplies will continue through until 2019.
The family owned Connecticut-based curling supplier will act as a sponsor of USA Curling, providing financial and advertising support to the national governing body.
Brooms Up, owned by Gary and Megan Suslavich, has been the preferred curling equipment supplier of USA Curling since the 2010-2011 season.
"We are pleased to extend and expand our relationship with Brooms Up Curling Supplies for many more years," said Rick Patzke, USA Curling chief executive.
"The first years of this partnership have helped each of our organisations grow individually as well as together.
"Forging a longer-term arrangement makes perfect sense as we both seek to continue to nurture and support the ongoing development of the sport throughout the United States."
As part of the agreement, USA Curling will provide Brooms Up with a range of promotional benefits over the coming years.
This will include logo placement on team uniforms, event signage and presence, to website and social media mentions.
"We are excited to be invited to extend our relationship with USA Curling as their preferred equipment supplier," said Megan Suslavich.
"As it creates many more opportunities to demonstrate our commitment to helping grow this unique and wonderful sport throughout America and beyond."
