Buying Guide: Plastic Spacers For Construction
Key purchase considerations
- Material and durability: Nylon, PP, and ABS offer insulation, corrosion resistance, and light weight. Choose a material based on environmental exposure and load requirements.
- Size variety and compatibility: Look for sets with multiple IDs, OD ranges, and thicknesses to cover different fixtures, tiles, and mounting scenarios.
- Non-threaded versus threaded: Non-threaded spacers are common for general spacing; threaded options are needed for some mounting plates or hardware.
