A standard wing toggle folds for insertion through a drilled hole and opens behind a hollow panel. Product-specific hole sizes and tested loads must come from the selected manufacturer's current data.
If an actuator bracket is supported by a hollow panel, its attachment must be assessed for the actual bracket load and the selected anchor and substrate. This toggle-bolt table alone does not establish whether that mounting arrangement is suitable.
Where springs or counterbalances are involved, calculate the actuator force over the full travel. The highest load may occur at a different position than the most obvious one.
The actuator stroke should also be checked against the useful motion, not just against the visible travel. End clearance, hard stops, bracket rotation, and wire routing can all reduce the usable stroke in the final build.
- Calculate actuator force at the worst bracket angle, not just at mid-stroke.
- Check stroke, retracted length, and extended length against the mechanism envelope.
- Confirm the structure can accept the higher loads created by a stronger actuator.
For a FIRGELLI actuator application, run the FIRGELLI actuator force calculator, then compare available stroke, force, and mounting envelope in the FIRGELLI linear actuator range. If the goal is to replace an existing unit, use the linear actuator replacement finder before assuming the new actuator is a direct fit.
Toggle Bolt Interactive Calculator
Select a listed bolt diameter and wallboard thickness from the cited 2024 TOGGLER sheet. The result is a table lookup for that product family, not a universal anchor rating or installation approval.
Equation Used
- Bolt diameter and wallboard thickness are restricted to rows in the cited standard wing-toggle sheet.
- Listed hole diameter comes from that sheet's installation table.
- Listed allowable and ultimate wallboard loads are copied from the cited product table; its tension and shear entries are equal for these rows.
- Entered drilled-hole difference is a dimensional comparison only.
- Wall condition, edge distance, spacing, fixture geometry, eccentricity, installation quality, dynamic load, ceiling use and code requirements are not evaluated.
Fold, Insert and Open
Rawlplug's spring-toggle instructions show the core sequence: drill the required hole, compress the wings, push them through the board, and tighten while pulling the fixture outward to keep the wings from spinning.
The schematic follows that deployment topology. It is not a dimensional installation drawing.
What This Calculator Does
The tool selects exact rows from the cited TOGGLER 2024 standard wing-toggle sheet for 1/8, 3/16 and 1/4 inch bolts in 3/8 through 3/4 inch wallboard. It reports the listed installation-hole diameter, listed allowable wallboard load, and a direct ultimate-load/divisor quotient.
The table lists equal tension and shear values for these wallboard rows. Other products, substrates and editions can differ.
Product-table Lookup
A = allowable-load table(d,t)
U = ultimate-load table(d,t)
Q = U/S
Delta = D - H
The manufacturer says A is based on a 4:1 factor. Q shows ultimate load divided by the entered comparison divisor; it is not an approved allowable load.
Worked Table Example
For the cited 1/4 inch wing toggle in 1/2 inch wallboard, the listed drill diameter is 5/8 inch, allowable load is 60 lb, and ultimate load is 240 lb. With S=4, the arithmetic quotient is also 60.0 lb. An entered 5/8 inch hole has zero dimensional difference.
Assumptions and Limits
- Reference context: the cited 2024 standard wing-toggle product sheet and manufacturer installation instructions.
- Calculated: exact table selection, ultimate/divisor arithmetic and entered-minus-listed hole difference.
- Not calculated: universal capacity, combined/eccentric/dynamic load, fixture leverage, fastener interaction, edge distance, spacing, ceiling suitability, substrate damage or condition, installation quality, required reliability, code compliance or safe attachment selection.
Frequently Asked Questions
Are these ratings universal?
No. They are rows from the cited TOGGLER standard wing-toggle sheet.
Is the ultimate/divisor quotient an allowable load?
No. Only the listed allowable value is manufacturer data.
Why can the quotient equal the listed allowable value at S=4?
The sheet states its allowable values use a 4:1 factor.
Does zero hole difference prove correct installation?
No.
Can loads from several anchors simply be added?
This calculator does not analyze load sharing or spacing.
Can this approve a TV, cabinet, grab bar or overhead fixture?
No. Use the selected product's instructions and qualified project-specific judgment.
