For square cut SUB15 profiles only. Use Moulded Push In Corners to easily join the corners of the Sub Frame.
Quick to fit, just loosely assemble the sub frame then tap the corners home.
The ‘flat’ face of the moulded plastic push-in corner has a unique combination of curves to create a slightly concave surface on the bonding face. This minimises the risk of the sharp corner of a mitred frame causing a bump on the face of the panel if it is flexed.
