Multiple Filled Arch Expansion Joint
- DFA ( Double Filled Arch
- TFA ( Triple Filled Arch )
Multiple Filled Arch Expansion Joint, with two or three filled arches, is recommended for greater movement capability for expansion and contraction where face-to-face dimensions are not limited.
With filled arch construction, it prevents the collection of solid mate-rials that may settle and remain in the archway.
The Onyx Expansion Joints reduce and isolate vibration, noise trans-mission and compensate movements in alignment due to wear and load stresses.
