T51010OPEN – 5-arm straight central connector | 3 mm steel

A clean central junction for your timber frame

Bring four horizontal beams together above a supporting post, without a roof pitch built into the connector. T51010OPEN combines one vertical arm with four straight horizontal arms for a level, five-arm junction.

Why choose OPEN?

The open design lets you insert and position beams from above. Different beam heights can be used when the timber width matches the selected connector and the joint configuration is suitable.

Technical specifications

• Steel thickness: 3 mm
• Configuration: five arms, one vertical and four horizontal
• Built-in pitch: 0°, no 5° slope
• Arm length: 200 mm
• Fixing holes: Ø6 mm, staggered

Choose your timber size

• 10/10: for 100 × 100 mm timber
• 12/12: for 120 × 120 mm timber
• 14/14: for 140 × 140 mm timber

Measure the actual finished timber width, including any coating, and verify the internal opening before ordering. OPEN offers flexibility in beam height, not universal compatibility in width.
